Battle of Prokhorovka

The Battle of Prokhorovka was fought near Prokhorovka, 87 km southeast of Kursk, on the Eastern Front during the Second World War as part of the Battle of Kursk in the Soviet Union. The 5th Guards Tank Army of the Soviet Red Army attacked the II SS-Panzer Corps of the German Wehrmacht in one of the largest tank battles in military history.

On 5 July 1943 the German command launched Operation Citadel with the aim of enveloping and destroying the Soviet forces in the Kursk salient. The operation was conducted by three German armies, with the 4th Panzer Army attacking from the south. Army Detachment Kempf was intended to protect the eastern flank of the 4th Panzer Army. Stavka, the Soviet High Command, was forewarned of the German intentions and had prepared a defence in depth along the routes of the planned German attack. They also massed a group of armies behind the front positions which they intended to use to launch their own offensive as a counterattack once the German strength had dissipated. This group of armies was called the Steppe Front, and its 5th Guards Tank Army was the armoured reserve with which they intended to seize the initiative.

A week into the German offensive the Soviets launched powerful counterattacks against the attackers. In the south at Prokhorovka, the 5th Guards Tank Army attacked the II SS-Panzer Corps, resulting in a large clash of armour just outside the settlement on 12 July 1943. The battle was fought across a stretch of land ranging in an arc of 20 km to the west and south of Prokhorovka. The 5th Guards Tank Army was decimated in the attack, but succeeded in preventing the Germans from capturing Prokhorovka and breaking through the third defensive belt to achieve operational freedom. Subsequently, the German offensive was cancelled and their forces withdrawn. The Red Army went over onto a general offensive and seized the strategic initiative on the Eastern Front, which it was to hold for the remainder of the conflict.

Background
As the rasputitsa or rainy season came to an end in 1943, both the German and Soviet commands considered their next step to bring the war to a successful conclusion. Stalin strongly desired to seize the initiative and attack the German forces, but was convinced by his senior commanders to take a defensive posture and allow the Germans to weaken themselves in attacking prepared positions, after which the Russian forces would go over onto the offensive. A similar strategy discussion occurred on the German side, with Field Marshal Eric von Manstein, arguing for a mobile defense which would give up terrain and allow the Russians to advance, followed by a series of sharp counterattacks against their flanks. For political reasons Hitler insisted upon going onto the offensive. The Kursk salient was chosen as the place.

The German offensive plan, called Unternehmen Zitadelle or Operation Citadel, envisioned an assault at the base of the Kursk salient from both the north and south. The double pincer attack was intended to cut off and envelop the Russian forces the German command thought would be massing west of Kursk for the next Russian offensive. The two spearheads were to meet behind the rail center of Kursk. From the south the 4th Panzer Army commanded by Generaloberst Hermann Hoth would drive northward. The III Panzer Corps of Army Detachment Kempf was to protect Hoth's right flank from counterattack by the Soviet strategic reserves known to be located further east. The 4th Panzer Army and Army Detachment Kempf were a part of Army Group South, which was commanded by General Manstein.

The German command postponed the launch of their offensive a number of times, due to Hitler's uncertainty over threats in the west, the need to refit the panzer divisions for the operation, and delays in the arrival of new armoured vehicles – in particular the Panther tank, but also larger numbers of the Tiger I tanks and the Ferdinand heavy tank destroyer. All this allowed the Soviets a great deal of time to prepare their defenses. The Soviets built a defence in depth designed to wear down the attacking panzer force. A series of defensive belts were created made up of extensive mine fields, anti-tank ditches, and anti-tank gun emplacements. The Voronezh Front, commanded by General Nikolai Vatutin, was tasked with defending the southern face of the salient. The Steppe Front was the strategic reserve force held behind the front to be brought up for the counteroffensive. It was under the command of General Ivan Konev.

German advance leading up to Prokhorovka
The Germans launched their attack on 5 July 1943 and met with heavy resistance. The number and density of Soviet anti-tank guns, minefields, and anti-tank ditches, and repeated counterattacks by large numbers of Soviet tanks were all much greater than had been anticipated, making a breakthrough far more difficult to achieve. The II SS-Panzer Corps was the only unit to advance significantly on the first day. The II SS-Panzer Corps benefitted from close air support provided by Luftflotte 4, whose aircraft helped destroy Soviet strong points and artillery positions. The Soviet defenders had a sizable amount of armour on hand in local reserve formations. Throughout the German offensive these were used to launch counterattacks from the 5th Guards Army, the 10th Tank Corps, and the 2nd Tank Corps. To the southeast the III Panzer Corps had great difficulty crossing the Northern Donets River. They eventually formed a bridgehead across by the morning of 6 July, but continued stubborn Soviet resistance meant they were unable to protect the east flank of the II SS-Panzer Corps.

By the end of 8 July, the II SS-Panzer Corps had advanced about 29 km and broken through the heavily fortified first and second defensive belts. However slow progress by the XLVIII Panzer Corps caused Hoth to shift elements of the II SS-Panzer Corps to the west to help the XLVIII Panzer Corps regain its momentum. On 10 July the full effort of the II SS-Panzer Corps was shifted back to its own forward progress. The direction of their advance now shifted from Oboyan due north to the northeast toward the town of Prokhorovka. Hoth had discussed this move with Manstein since early May, and it was a part of the 4th Panzer Army plan since the outset of the offensive. The Corps reoriented itself to the northeast and the attack towards Prokhorovka commenced. By this time the Soviets had shifted reserve formations into its path. The defensive positions were manned by the 2nd Tank Corps reinforced by the 9th Guards Airborne Division and 301st Anti-tank Artillery Regiment, both from the 33rd Guards Rifle Corps.

In the ensuing attacks, Leibstandarte had met with the most success, penetrating into the third Soviet defensive belt. They had moved up the Psel corridor, cleared Soviet resistance at the "October" Soviet state farm (Совхоз Октябрьский), crossed a fifteen-foot-deep antitank ditch at the base of Hill 252.2 and seized the hill itself after a brief but bloody battle. By days end on 11 July they were only 3 km from Prokhorovka. To its north the panzergrenadiers of Totenkopf achieved a bridgehead across the Psel and tanks had been brought across, but they had yet to take Hill 226.6 and there was a 5 kilometers gap between Totenkopf and  Leibstandarte. To the south Das Reich had also met stiff resistance and lagged behind, some 4 km to the south. Leibstandarte's flanks were exposed to both the north and south, placing them under sporadic counterattacks from the 95th Guards Rifle Division and the remnants of 2nd Tank Corps.

For the Soviets the 5th Guards Tank Army had been moving up from its reserve position since 6 July, traveling at night to avoid detection. They covered the 390 km over three nights, reaching the area of Prokhorovka during the night of 9 July.

Opposing forces
The battle was fought primarily between the 1st SS-Panzergrenadier Division Leibstandarte Adolf Hitler and the 5th Guards Tank Army, whose 29th and 18th Tank Corps were fresh formations brought up from the Soviet strategic reserve. These units provided the greatest number of tanks in the attack. Infantry support to the attack was provided by another reserve formation, the 9th Airborne Guard Rifle Division. Many historians consider the units engaged in broader terms, and include the entire II SS-Panzer Corps on the German side. On the Soviet side, in addition to the 5th Guards Tank Army and the 5th Guards Mechanized Corps, they include the depleted formations of the local defending units, the 5th Guards Army, the 2nd Tank Corps, and the 2nd Guards Tank Corps, whose attack was directed toward the 2nd SS Das Reich Division, the 23rd Guards Rifle Corps, and some of the remaining formations of the 1st Tank Army which attacked the 3rd SS Totenkopf Division.

German
The German forces involved in the battlefield of Prokhorovka were from the three Waffen-SS divisions of the II SS-Panzer Corps: the 1st SS-Panzergrenadier Division Leibstandarte Adolf Hitler, 2nd SS-Panzergrenadier Division Das Reich, and 3rd SS-Panzergrenadier Division Totenkopf. For the evening of 11 July, the serviceable armour strength of the II SS-Panzer Corps was 294 tanks and assault guns – of which 15 were Tigers. The armoured strength of the 1st, 2nd, and 3rd SS-Panzergrenadier Divisions were 77, 95, and 122 tanks and assault guns respectively.

Soviet
The main Soviet armoured formation involved in the battle was the 5th Guards Tank Army. Prior to the engagement on 12 July, the 5th Guards Tank Army fielded 793 tanks and 37 to 57 self-propelled guns for a total of approximately 840 armoured fighting vehicles. About two-thirds of these tanks were the T-34, with the remainder being the T-70 light tank, along with some 35 Churchills.

Soviet air support over the battle was provided by the 2nd Air Army and the 17th Air Army. Both had suffered significant losses over the previous week's fighting. On 12 July the 2nd Air Army still had some 472 aircraft operational, while the 17th Air Army had 300 remaining operational aircraft.

German plans for 12 July


General Paul Hausser, the commander of the II SS-Panzer Corps, had expected to continue his advance on Prokhorovka, and late on the evening of 11 July issued orders for a classic maneuver battle for the following day's attack. The Soviets were known to have a great many anti-tank guns dug in on the west slopes before Prokhorovka, making a direct attack by Leibstandarte very difficult. The plan was for the attack to begin north of the Psel river with Totenkopf driving northeast to the Karteschewka-Prokhorovka road, then striking southeast to assault the Soviet positions at Prokhorovka from the flank and rear. The 1st and 2nd SS-Panzer divisions were to wait until Totenkopf's attack had disrupted the Russian positions. Once the Soviets at Prokhorovka were under attack from Totenkopf, the Leibstandarte was to join in, advancing through the main Soviet defenses on the west slope before Prokhorovka. To Leibstandarte's right, Das Reich was to advance as well, moving east to the high ground south of Prokhorovka, then turning south away from Prokhorovka to roll up the Soviet line and force a gap in the Soviet defenses. The German VIII Fliegerkorps was to make their main effort in support of the advance of the II SS-Panzer Corps, with the XLVIII Panzer Corps to the west assigned limited air resources.

Unbeknownst to Hausser, on the night of 11/12 July Lieutenant General Pavel Rotmistrov had moved his 5th Guards Tank Army up to an assembly area just below Prokhorovka in preparation for a massive armoured attack the following day. Throughout the night the German troopers could hear the ominous sounds of Russian tank engines to the east as the 18th and 29th Tank Corps moved into their assembly areas.

Soviet plans for 12 July
On 11 July Vatutin ordered that the following day the armies of the Voronezh Front were to go over onto the offensive. This counterattack was to be the southern element of a general Soviet offensive. The forces of the Steppe Front, including the powerful 5th Guards Tank Army, had been brought up from reserve to smash the forces spearheading the German attack. The 5th Guards Tank Army was supported by infantry of the 5th Guards Army and the 69th Army. Five artillery regiments, one artillery brigade, and one artillery division were on hand to support the assault. To the immediate south of the 5th Guards Tank Army, the 2nd Guards Tank Corps and the depleted 2nd Tank Corps were to attack the positions of the Das Reich division. The 5th Guards Mechanized Corps was held as reserve north of Prokhorovka. Rotmistrov ordered that his tankers were to move forward at speed to engage the German armour thus nullifying the advantages the Ferdinands and Tiger tanks had in the range and firepower of their 88 mm guns. He believed the more maneuverable T-34 would be able to quickly close and obtain effective flanking shots against the German heavy tanks. In making the dispositions of his forces for the attack, he realized Leibstandarte was already in possession of his planned assembly areas.Rotmistrov was compelled to hastily rewrite his orders for the 5th Guards Tank Army.

Late on the night of 12 July, the Soviet command was informed that German forces had crossed the Northern Donets at Rzhawes (also known as Rzhavets). This jeopardised Rotmistrov's entire plan by threatening the flank of the 5th Guards Tank Army. Early on 12 July, Vatutin ordered Rotmistrov to send reinforcements to the Soviet forces facing the III Panzer Corps. He organised a task force under the command of his deputy, General K. G. Trufanov. The command consisted of the 26th Tank Brigade from the 2nd Guards Tank Corps, the 11th and 12th Guards Mechanized Brigades from the 5th Guards Mechanized Corps, and the 53rd Guards Tank Regiment from the 5th Guards Tank Army. Other units from the reserve also were attached to the group on its way south. In doing so Rotmistrov had committed over half of his reserves to an essential ad-hoc advance before the battle of Prokhorovka began. As to air support, Vatutin focused the effort of the Red Air Force on the XLVIII Panzer Corps to the west.

The battle
By 06:00 Leibstandarte's headquarters was receiving reports of the sound of a great number of tank engines as the Russian tankers prepared for their advance. The Soviets commenced a short artillery barrage between 06:00 and 06:15. As the last shells fell at 06:30 Rotmistrov radioed the code words "Stal! Stal! Stal!" ("Steel, Steel, Steel!") – the order to commence the attack. With that the Soviet armour of the 5th Guards Tank Army began their advance.

Down off the west slopes before Prokhorovka came the massed Soviet armour of five tank brigades. The T-34s and T-70s of the 29th and 18th Tank Corps approached at speed, firing as they came. The five armoured brigades advancing toward the positions of the Leibstandarte had 60 to 65 tanks in each brigade. As the Russian tankers rolled down the corridor they carried on their decks the men of the 9th Parachute Division. Around 500 tanks and self-propelled guns approached the German positions in two massive waves, with 430 tanks in the first echelon and 70 more in the second.

Exhausted from the previous fighting, the troops of Leibstandarte were not expecting an immediate resumption of the fighting until later in the day, and were largely taken by surprise. A battalion from Leibstandarte's 2nd SS-Panzergrenadier regiment was situated on the reverse slope of Hill 252.2, which they had taken the day before. At the base of Hill 252.2 was a Soviet anti-tank ditch. German outposts commenced firing purple warning flares signaling a tank attack. Soon purple flares were being fired all across the front. Obersturmfuhrer Rudolf von Ribbentrop of the 1st SS-Panzer Regiment's 2nd Battalion knew that a major attack was underway. He ordered his company of seven Panzer IVs to start up. They followed him over a pioneer-built bridge across the ditch and fanned out onto the lower slope of Hill 252.2. Above him Joachim Peiper's 2nd SS-Panzergrenadiers and their armoured half-tracks on the crest of Hill 252.2 were being overrun. As Ribbentrop's tankers spread out on the lower slope he looked up the hillside. "In front of me appeared fifteen, then twenty, then thirty, then forty tanks. Finally there were too many of them to count. The T-34s were rolling toward us at speed, and carrying mounted infantry."

As the Soviet tankers charged down the west slope of Hill 252.2 a hotly contested tank battle ensued. A Panzer IV to Ribbentrop's right was set ablaze. Soon the company was swamped by the seemingly endless number of Russian tanks coming down the hill. The Soviet tanks were firing on the move, greatly reducing their accuracy. Rotmistrov's tactic to close at speed also disrupted the control and co-ordination of the Soviet tank formations. In fact Soviet intelligence had greatly overestimated the numbers of Ferdinands and Tigers possessed by the II SS-Panzer Corps. In actuality there were no Ferdinands with the 4th Panzer Army, as they were all deployed to the north with the 9th Army. The three divisions of the II SS-Panzer corps had fifteen Tiger tanks between them, with ten of those to the north of the Psel river with Totenkopf. Leibstandarte had only four Tigers operational, while Das Reich had but one.

The advance of Soviet armour was held up at the base of the Hill 252.2 when they reached the anti-tank ditch. Some vehicles crashed into the 15-foot ditch while others moved along the edge looking for a way to cross. Heavy firing occurred between the Soviet armour and the two other companies of the 1st SS-Panzer Battalion on the opposite side of the ditch, while the Russian tanks searched for a route across. Meanwhile, with the passage of the first waves of Russian tanks Peiper's surviving panzergrenadiers emerged from trench lines to engage the Soviet paratroopers and attack the Russian tanks with magnetic shaped charges. Twenty of the battalion's half-tracks were lost in the fighting. Some were destroyed when they attempted to ram the much heavier Russian tanks in an effort to stop them from destroying the company.

Above the battlefield, the 2nd and 17th Air Armies flew 893 sorties compared to the VIII Fliegerkorps's 654 sorties over the southern part of the salient. However, most of the Soviet sorties flown that day were flown against the XLVIII Panzer Corps to the west and the III Panzer Corps to the south. Over the Prokhorovka battlefield, the Luftwaffe dominated the air, although low clouds in the morning and thunderstorms in the afternoon inhibited operations by both sides. Formations of Stukas, including a small number of experimental 3.7 cm BK 37 cannon-equipped G-2 variants, commanded by Staffelkapitan Hans-Ulrich Rudel, Fw 190 fighter-bombers and Hs 129 ground-attack aircraft equipped with 3 cm anti-tank cannon attacked the Soviet formations. The 31st Tank Brigade reported: "We suffered heavy losses in tanks through enemy artillery and aircraft. At 10:30 our tanks reached the Komsomolets State Farm, but due to continuous air attacks, they were unable to advance any further and shifted to the defence." The tank brigade also reported: "our own air cover was fully absent until 13:00." The 5th Guards Tank Army reported: "the enemy's aircraft literally hung above our combat formations throughout the entire battle, while our own aircraft, and particularly the fighter aviation, was totally insufficient."

By the end of the day, Leibstandarte still held Hill 252.2 and had lost no ground, but was exhausted by the struggle turning back the five brigades of the 5th Guards Tank Army. To its left, Totenkopf had succeeded in capturing Hill 226.6 and its panzer group had advanced along the north bank of the Psel to reach the Karteschevka-Prokhorovka road, 8 km northwest of Prokhorovka. Though its hold on the forward ground was tenuous, it was in position to outflank the Soviet forces at Prokhorovka. Das Reich had been forced onto the defensive by the 2nd Guards Tank Corps and 2nd Tank Corps. Unable to undertake its planned attack, its panzer group was limited to counterattacks against the Soviet armour. For their part the Soviet 5th Tank Army suffered very heavy losses in armour, The Soviet assault had been turned back and Rotmistrov was forced to shift his command to defence.

Following the main engagement
On the night of 12 July, Vatutin ordered the Soviet forces facing the II SS-Panzer Corps and III Panzer Corps to take a defensive stance the next day. The 1st Tank, 6th Guards Armies, and the 32nd Guard Rifle Corps (of the 5th Guards Army) were to continue their attack on the XLVIII Panzer Corps. The Red Air Force was to continue focusing its effort on the III Panzer Corps. Orders issued by the II SS-Panzer Corps for 13 July required Totenkopf to consolidate its gains of the previous day and then attack across the Psel into the northwestern flank of Soviet forces around Prokhorovka. Leibstandarte Adolf Hitler was to strengthen its front line and co-ordinate its attack on Prokhorovka from the south with Totenkopf's attack from the northwest. Das Reich was tasked with consolidating and strengthening its front line and to prepare for an offensive operation to link up with the III Panzer Corps.

On the morning of 13 July, Soviet units launched a reconnaissance-in-force against Totenkopf. By afternoon, this action had developed into local counterattacks by the 5th Guards Mechanized Corps and the 33rd Guards Rifle Corps, primarily focused on Totenkopf's left flank. These Soviet attacks prevented Totenkopf from attacking to the south against the Soviet positions at Prokhorovka. Around noon, Leibstandarte was given orders to attack northward toward the Psel River, to the west of Prokhorovka, to consolidate its front line with Totenkopf's positions. This attack confronted the fortified defensive positions held by the 33rd Guards Rifle Corps supplemented by the remnants of the 18th and 29th Tank Corps, and the attack was unsuccessful. That afternoon, Totenkopf was ordered to abandon the narrow and now exposed salient northwest of Prokhorovka and return to more defendable positions along the north bank of the Psel River. Despite Soviet attempts to sever the salient, the division successfully completed its withdrawal by nightfall.

Aftermath
On the night of 9–10 July 1943, the Allies invaded Sicily. This event, combined with the violent attacks by strong Soviet armoured reserves at Prokhorovka and the Soviet counteroffensive of Operation Kutuzov against the flank and rear of Model's 9th Army on 12 July, led Adolf Hitler to summon Manstein and Kluge to his H.Q. in East Prussia, the Wolfsschanze, on 13 July. He ordered the generals to terminate Operation Citadel. Kluge welcomed the decision, as he was already in the process of withdrawing units of the 9th Army from the Kursk salient to deal with the Russian attacks.

Manstein was greatly disappointed. He argued that his forces were now on the verge of achieving a major breakthrough. With the III Panzer Corps about to link up with the II SS-Panzer Corps at Prokhorovka, and his operational reserve, the XXIV Panzer Corps, available, they were halting the offensive just as the moment of victory was in hand. With an eye toward the west, Hitler was unwilling to continue the offensive. Manstein persisted, proposing that his forces should at least destroy the Soviet reserves in the southern Kursk salient before Citadel was finally terminated, so the Soviet fighting capacity in the sector would be depleted for the rest of the summer. Hitler agreed to continue offensive operations in the southern salient until Manstein's goal was achieved.

Operation Roland
Manstein hastily put together the plans for Operation Roland, realizing that he only had a few days to conduct the operation before he lost the SS-Panzer Corps. The plan called for Das Reich to attack east and south and link up with III Panzer Corps, which would attack to the northwest. Leibstandarte Adolf Hitler and Totenkopf were to anchor the left and northern flanks of Das Reich. Once the link was achieved and the Soviet forces encircled, the Soviet defense would be crippled and Prokhorovka would likely fall shortly thereafter. The goal of the operation was to destroy the Soviet armoured reserve massed in the southern sector of the Kursk salient, and thereby check Soviet offensives for the remainder of the summer.

The orders for Operation Roland were issued in the closing hours of 14 July 1943. However, following Hitler's meeting with Manstein, Hitler countermanded the XXIV Panzer Corps' deployment to the Kursk salient, sending them on 14 July to support the 1st Panzer Army to the south. The assault began at 0400 on 15 July. Following a brief artillery barrage, the Der Fuhrer panzergrenadier regiment of Das Reich struck out for the high ground south-west of Pravorot, evicting the remnants of the 2nd Guards Tank Corps from the village of Belenikhino following violent house-to-house and hand-to-hand fighting. The panzer regiment of the division fought off a series of counterattacks, destroying a number of T-34s in the process. The Soviets were forced to withdraw to the east. A new line was taken, and Zhukov ordered elements of the 10th Guards Mechanized Brigade out of reserve to reinforce the position. To the south, the 7th Panzer Division made contact with Das Reich, but Trufanov, commanding the Soviet forces in the gap, was aware of the threat and was conducting a fighting withdrawal. Though the Russians had to abandon a substantial number of anti-tank guns, the link-up failed to entrap very many Soviet forces. Operation Roland failed to produce a decisive result. Following orders issued late on 15 July, Totenkopf began withdrawing from its positions north of the Psel River as the II SS-Panzer Corps assumed a defensive stance.

On 17 July the Soviet Southwestern and Southern Fronts launched a major offensive across the Mius and Donets Rivers against the southern wing of Army Group South, pressing upon the 6th Army and 1st Panzer Army. In the early afternoon of 17 July, Operation Roland was terminated with an order for the II SS-Panzer Corps to begin withdrawing from the Prokhorovka sector back to Belgorod. The 4th Panzer Army and Army Detachment Kempf anticipated the order and began executing it as early as the evening of 16 July. Leibstandarte's tanks were distributed between Das Reich and Totenkopf and the division was hastily redeployed to Italy. Das Reich and Totenkopf were dispatched south to meet the new Soviet offensive.

Casualties and losses
Losses are difficult to establish for either combatant. Tank losses attributed to the Germans vary, in part due to the Wehrmacht's methodology for counting and reporting equipment losses. Equipment that could be recovered and repaired were listed as such. Equipment that could not be repaired or that had to be abandoned was counted as losses. Likewise, reliable figures for tank and personnel casualties for the Soviets in the battle of Prokhorovka are difficult to establish.

German
The II SS-Panzer Corps reported 842 casualties, killed, wounded, or missing for 12 July. Since the Germans controlled the battlefield of Prokhorovka right up till 17 July, they were able to recover most of their disabled armoured vehicles. German archival data for II SS-Panzer Corps indicates that the II SS-Panzer Corps lost three to five tanks. Records from the three divisions that made up the Corps indicate Leibstandarte Adolf Hitler suffered three tank losses in the battle, two Panzer IVs and one Tiger. The strength for the remaining two divisions were 103 and 121 operational tanks and assault guns respectively. By the end of 16 July, the II SS Panzer corps had almost the same number of serviceable tanks it had at the beginning of the battle.

Divisional returns show that SS-Panzer Corps had 294 operable panzers and assault guns on 12 July and 251 on 13 July. Allowing for the possibility that some repaired tanks were returned to service on 13 July, these numbers indicate that at least 43 SS-Panzer Corps vehicles became inoperable during the battle of Prokharovka. That number includes all 10 Tigers belonging to Totenkopf and one belonging to Leibstandarte. All of the inoperable Tiger tanks were repairable however, and none were write-offs. An estimated total of between 60 and 80 of SS-Panzer Corps' armored vehicles became inoperable in combat on 12 July. On 12 July, Schlachtgeschwader 1 and its attached squadron of Stukas reported eleven aircraft damaged, of which six were total write-offs, all by Soviet flak.

Soviet
Exact Soviet losses for 12 July are not known, but have been estimated by military historians. Personnel losses at Prokhorovka were estimated by Bergström to have been as high as 5,500 men. For equipment losses, Glantz and House estimate the 5th Guards Tank Army lost at least 400 of their 800-plus tanks in its attacks on 12 July. George Nipe puts the losses in armour as between 600 and 650 tanks. 5th Guards Tank Army were estimated by Koltunov and Soloviev to have been about 300 tanks and self-propelled guns. A document prepared on 17 July 1943 by the 5th Guards Tank Army Headquarters summarised the combat losses incurred by the formation from 12 to 16 July inclusive for all of its five corps, as well as divisions, brigades, and other smaller units directly subordinate to the army headquarters. The document reported the following irrevocable losses: 222 T-34s, 89 T-70s, 12 Churchill tanks, 8 SU-122, 3 SU-76, and 240 support vehicles. The document reported damaged vehicles still under repair as 143 T-34s, 56 T-70s, 7 Churchill tanks, 3 SU-122, 3 SU-76, and no figures for support vehicles. The document reported personnel casualties as 2,940 killed in action, 3,510 wounded in action, and 1,157 missing in action. This makes for a total of 7,607 casualties.

Outcome
Debate exists over the significance and outcome of the battle. The Battle of Prokhorovka may have been a tactical victory for the Wehrmacht, but was not an operational victory. A great number of Soviet tanks were destroyed and the striking power of the 5th Guards Tank Army was temporarily degraded, but the Germans were unable to take Prokhorovka or break through into open ground. For the Soviets, the massive armoured attack of 12 July failed to destroy the II SS-Panzer Corps or throw the Germans onto the defensive, but the attacking German units were exhausted by the effort and their advance was checked. Neither the 5th Guards Tank Army nor the II SS-Panzer Corps accomplished their objectives for the day. The battle is generally considered a tactical success for the Germans due to the high loss of Soviet armour. Ultimately there was no German breakthrough at Prokhorovka, and with the end of Operation Citadel the strategic initiative permanently swung over to the Red Army.
