NMS Sublocotenent Ghiculescu

NMS Sublocotenent Ghiculescu was a specialized ASW gunboat of the Romanian Navy. Initially built as a French warship in late World War I, she was purchased by Romania in 1920 and fought during World War II, sinking two submarines and one motor torpedo boat. After 1 year of Soviet service, she was returned to Romania and served as a survey vessel until 2002.

Construction and specifications
Sublocotenent Ghiculescu was a gunboat of the French Friponne class. She was built at Arsenal de Brest, being launched in 1917 and commissioned by the French Navy as Mignonne in 1918. She was sold to Romania in January 1920. The warship displaced 350 tons, measuring 60.2 meters in length, with a beam of 7 meters and a draught of 3.6 meters. Power plant consisted of two Sulzer diesel engines powering two shafts, resulting in a top speed of 15 knots. Her armament consisted of two 100 mm naval guns and two depth-charge throwers. She had a range of 3,000 nautical miles at a speed of 10 knots and a crew of 50.

Service
During World War II, her armament was changed. Her two 100 mm naval guns were replaced by one 88 mm naval/anti-aircraft gun, one 37 mm anti-aircraft gun and one 20 mm anti-aircraft gun.

She escorted a total of 17 Axis convoys in the Black Sea.

On 1 October 1942, the Soviet M-class submarine M-118 attacked and sank the German transport ship Salzburg, which was carrying on board 2,000 Soviet prisonsers of war. After attacking, the submarine was located by a German BV138C flying boat, and Sublocotenent Ghiculescu together with sister ship Stihi Eugen were sent to the scene. The two Romanian gunboats attacked the Soviet submarine with depth-charges, sinking her with all hands.

On 18 April 1944, during the evacuation of the Crimea, the Soviet Leninets-class submarine L-6 was sunk with depth charges near Sevastopol by the Sublocotenent Ghiculescu, aided by the German submarine chaser UJ-104.

During the night of 27 April, a convoy escorted by the Romanian gunboat Sublocotenent Ghiculescu, the German submarine hunter UJ-115, one R-boat, two KFK naval trawlers and 19 MFPs (including the Romanian PTA-404 and PTA-406) engaged the Soviet G-5-class motor torpedo boats TKA-332, TKA-343 and TKA-344, after the three attacked and damaged the German submarine hunter UJ-104. Ghiculescu fired tracer rounds from her 88 mm gun, enabling the entire escort group to locate the two Soviet MTBs and open fire. TKA-332 was hit and sunk.

She was captured by Soviet forces in September 1944 and was commissioned as Angara. In October 1945, she was returned to Romania and served as a survey vessel until 2002.
