The Boeing RC-135 is a family of large reconnaissance aircraft built by Boeing and used by the United States Air Force to support theater and national level intelligence consumers with near real-time on-scene collection, analysis and dissemination capabilities. Based on the C-135 Stratolifter airframe, various types of RC-135s have been in service since 1961. Unlike the C-135 and KC-135 which are recognized by Boeing as the Model 717, the RC-135 is internally designated as the Model 739 by the company. Many variants have been modified numerous times, resulting in a large variety of designations, configurations, and program names.

Design and development[edit | edit source]
The first RC-135 variant, the RC-135A, were ordered in 1962 by the United States Air Force to replace the Boeing RB-50 Superfortress. Originally nine were ordered but this was later reduced to four. Boeing allocated the variant the designation Boeing 739-700 but they were modified variant of the KC-135A then in production. They used the same J57-P engines of the tanker variant but carried cameras in bay just aft of the nose undercarriage bay where the forward fuel tank was normally located. They had no refueling system fitted and they were to be used for photographic and surveying tasks.
The next variant ordered was the RC-135B to be used as an electronic intelligence aircraft to replace the Boeing RB-47H Stratojet on ELINT duties. Similar to the earlier variants, the RC-135Bs were fitted with TF-33 turbofans rather than the older J57s. These ten aircraft were delivered directly into storage in 1965 while they awaited fitment of an improved electronics suite. By 1967 they had emerged as RC-135Cs and were all delivered that year. The refueling boom was not fitted and the boom operators station was used as a camera bay, for a KA-59 camera. Externally the aircraft were also fitted with sideways looking airborne radar (SLAR) antenna on either the lower forward fuselage.
The RC-135Bs were the last of the new aircraft built, all the RC variants that followed were modified aircraft, either from earlier RC variants or from tankers.
In 2005, the RC-135 fleet completed a series of significant airframe, navigational and power-plant upgrades which include re-engining from the Pratt & Whitney TF-33 to the CFM International CFM-56 (F-108) engines used on the KC-135R and T Stratotanker and upgrade of the flight deck instrumentation and navigational systems to the AMP standard. The AMP standard includes conversion from analog readouts to a digital "glass cockpit" configuration.
Operational history[edit | edit source]
The current RC-135 fleet is the latest iteration of modifications to this pool of aircraft going back to the early 1960s. Initially employed by Strategic Air Command for reconnaissance, the RC-135 fleet has also participated in every armed conflict involving U.S. assets during its tenure. RC-135s supported operations in Vietnam, the Mediterranean for Operation El Dorado Canyon, Grenada for Operation Urgent Fury, Panama for Operation Just Cause, the Balkans for Operations Deliberate Force and Allied Force, and Southwest Asia for Operations Desert Shield, Desert Storm, Enduring Freedom and Iraqi Freedom. RC-135s have maintained a constant presence in Southwest Asia since the early 1990s.
All RC-135s were originally operated by Strategic Air Command. Since 1992 they have been assigned to Air Combat Command. The RC-135 fleet is permanently based at Offutt Air Force Base, Nebraska and operated by the 55th Wing, using forward operating locations worldwide. The 55th Wing operates 22 platforms in three variants: three RC-135S Cobra Ball, two RC-135U Combat Sent, and 17 RC-135V/W Rivet Joint.
On August 9, 2010, the Rivet Joint recognized its 20th anniversary of continued service in Central Command, dating back to the beginning of Desert Storm. This represents the longest unbroken presence of any aircraft in the Air Force's inventory. During this time it has flown over 8,000 combat missions supporting air and ground forces of Operations Desert Storm, Desert Shield, Northern Watch, Southern Watch, Iraqi Freedom and Enduring Freedom, which continues to this day.
On 22 March 2010 the British Ministry of Defence announced that it had reached agreement with the US Government to purchase three RC-135W Rivet Joint aircraft along with associated ground systems to replace the Nimrod R1, which was subsequently retired in June 2011. The aircraft are scheduled to be delivered between 2014 and 2018.
Variants[edit | edit source]
KC-135A Reconnaissance Platforms[edit | edit source]
At least three KC-135A tankers were converted into makeshift reconnaissance platforms with no change of Mission Design Series (MDS) designation. KC-135As 55-3121, 59-1465, and 59-1514 were modified beginning in 1961. That year the Soviet Union announced its intention to detonate a 100-megaton-of-TNT (420 PJ) thermonuclear device on Novaya Zemlya, the so-called Tsar Bomba. One aircraft (probably either 55-3121 or 59-1465) was modified under the Big Safari program to the Speed Light configuration in order to obtain intelligence information on this test. The success of this mission prompted the conversion of two additional aircraft for intelligence gathering duties.
KC-135R Rivet Stand / Rivet Quick[edit | edit source]
Not to be confused with the CFM F108-powered KC-135R tanker, the KC-135R MDS was applied beginning in July 1967 to the three KC-135A reconnaissance aircraft under the Rivet Stand program name. The three aircraft were 55-3121, 59-1465, 59-1514, with KC-135A 58-0126 converted in 1969 to replace 59-1465 which had crashed at Offutt AFB, Nebraska in 1967. Externally the aircraft had varied configurations throughout their lives, but generally they were distinguished by five "towel rail" antennas along the spine of the upper fuselage and a radome below the forward fuselage. The first three aircraft retained the standard tanker nose radome, while 58-0126 was fitted with the 'hog nose' radome commonly associated with the RC-135. A trapeze-like structure in place of the refueling boom which was used to trail an aerodynamic shape housing a specialized receiver array (colloquially known as a "blivet") on a wire was installed. This was reported to be used for "Briar Patch" and "Combat Lion" missions. There were four small optically flat windows on each side of the forward fuselage. On some missions a small wing-like structure housing sensors was fitted to each side of the forward fuselage, with a diagonal brace below it. With the loss of 59-1465, KC-135A 58-0126 was modified to this standard under the Rivet Quick operational name. All four aircraft have now been lost or stripped of the Rivet Stand fitting.
KC-135T Cobra Jaw[edit | edit source]
KC-135R 55-3121 Rivet Quick was modified in 1969 by Lockheed Air Services to the unique KC-135T configuration under the Cobra Jaw program name. Externally distinguished by the 'hog nose' radome, the aircraft also featured spinning "fang" receiver antennas below the nose radome, a large blade antenna above the forward fuselage, a single 'towel rail' antenna on the spine, teardrop antennas forward of the horizontal stabilizers on each side, and the trapeze-like structure in place of the refueling boom. The aircraft briefly carried nose art consisting of the Ford Cobra Jet cartoon cobra. It was later modified into an RC-135T Rivet Dandy.
RC-135A[edit | edit source]
Four RC-135A (63-8058,63-8059, 63-8060, & 63-8061) were photo mapping platform utilized briefly by the Air Photographic & Charting Service, based at Turner AFB, Georgia and later at Forbes AFB, Kansas as part of the 1370th Photographic Mapping Wing . The mission was soon taken over by satellites, and the RC-135As were de-modified and used as staff transports, in the early 1980s they were converted to KC-135D's. Due to delays in fitting their original equipment, the RC-135As were the last of the entire C-135 series delivered to the USAF. The Boeing model number for the RC-135A is 739-700.
RC-135B[edit | edit source]
The as-delivered version of the RC-135. The RC-135B was never used operationally, as it had no mission equipment installed by Boeing. The entire RC-135B production run of ten aircraft was delivered directly to Martin Aircraft in Baltimore, Maryland for modification and installation of mission equipment under the Big Safari program. Upon completion, the RC-135Bs were re-designated RC-135C. The Boeing model number for the RC-135B is 739-445B.
RC-135C Big Team[edit | edit source]
Modified and re-designated RC-135B aircraft used for strategic reconnaissance duties, equipped with the AN/ASD-1 electronic intelligence (ELINT) system. This system was characterized by the large 'cheek' pods on the forward fuselage containing the Automated ELINT Emitter Locating System (AEELS - not Side Looking Airborne Radar - SLAR, as often quoted), as well as numerous other antennae and a camera position in the refuelling pod area of the aft fuselage. The aircraft was crewed by two pilots, two navigators, numerous intelligence gathering specialists, and airborne linguists. When the RC-135C was fully deployed, SAC was able to retire its fleet of RB-47H Stratojets from active reconnaissance duties. All ten continue in active service as either RC-135V Rivet Joint or RC-135U Combat Sent platforms.
RC-135D Office Boy / Rivet Brass[edit | edit source]
The RC-135Ds, originally designated KC-135A-II, were the first reconnaissance configured C-135's given the 'R' MDS designation, although they were not the first reconnaissance-tasked members of the C-135 family. They were delivered to Eielson Air Force Base, Alaska in 1962 as part of the Office Boy Project. Serial numbers were 60-356, 60-357, and 60-362. The aircraft began operational missions in 1963. These three aircraft were ordered as KC-135A tankers, but delivered without refueling booms, and known as "falsie C-135As" pending the delivery of the first actual C-135A cargo aircraft in 1961. The primary Rivet Brass mission flew along the northern border of the Soviet Union, often as a shuttle mission between Eielson and RAF Upper Heyford, Oxfordshire, and later RAF Mildenhall, Suffolk, UK. The RC-135D was also used in Southeast Asia during periods when the RC-135M (see below) was unavailable. In the late 1970s, with the expansion of the RC-135 fleet powered by TF33 turbofan engines, the RC-135Ds were converted into tankers, and are currently in the fleet as KC-135Rs.
RC-135E Lisa Ann / Rivet Amber[edit | edit source]
Originally designated C-135B-II, project name Lisa Ann, the RC-135E Rivet Amber was a one-of-a-kind aircraft equipped with a large 7 MW Hughes Aircraft phased-array radar system. Originally delivered as a C-135B, 62-4137 operated from Shemya Air Force Station, Alaska from 1966-1969. Its operations were performed in concert with the RC-135S Rivet Ball aircraft (see below). The radar system alone weighed over 35,000 pounds and cost over US$35 million (1960 dollars), making Rivet Amber both the heaviest C-135-derivative aircraft flying and the most expensive Air Force aircraft for its time. The radiation generated by the radar was sufficient to be a health hazard to the crew, and both ends of the radar compartment were shielded by thick lead bulkheads. This prevented the forward and aft crew areas from having direct contact after boarding the aircraft. The system could track an object the size of a soccer ball from a distance of 300 miles (480 km), and its mission was to monitor Soviet ballistic missile testing in the reentry phase. The power requirement for the phased array radar was enormous, necessitating an additional power supply. This took the form of a podded Lycoming T55-L5 turboshaft engine in a pod under the left inboard wing section, driving a 350kVA generator dedicated to powering mission equipment. On the opposite wing in the same location was a podded heat exchanger to permit cooling of the massive electronic components on board the aircraft. This configuration has led to the mistaken impression that the aircraft had six engines. On June 5, 1969, Rivet Amber was lost on a ferry flight from Shemya to Eielson AFB for maintenance, and no trace of the aircraft or its crew was ever found.
RC-135M Rivet Card[edit | edit source]
The RC-135M was an interim type with more limited ELINT capability than the RC-135C but with extensive additional COMINT capability. They were operated by the 82d Reconnaissance Squadron during the Vietnam War from Kadena AB, gathering signals intelligence over the Gulf of Tonkin and Laos with the program name Combat Apple (originally Burning Candy). There were six RC-135M aircraft, 62-4131, 62-4132, 62-4134, 62-4135, 62-4138 and 62-4139, all of which were later modified to and continue in active service as RC-135W Rivet Joints by the early 1980s.
RC-135S Nancy Rae / Wanda Belle / Rivet Ball[edit | edit source]
Rivet Ball was the predecessor program to Cobra Ball and was initiated with a single RC-135S (serial 59-1491, formerly a JKC-135A) on December 31, 1961. The aircraft first operated under the Nancy Rae project name as an asset of Air Force Systems Command and later as an RC-135S reconnaissance platform with Strategic Air Command under the project name Wanda Belle. The name Rivet Ball was assigned in January 1967. The aircraft operated from Shemya AFB, Alaska. Along with most other RC-135 variants, the RC-135S had an elongated nose radome housing an S band receiving antenna. The aircraft was characterized by ten large optically flat quartz windows on the right side of the fuselage used for tracking cameras. Unlike any other RC-135S, Rivet Ball also had a pleixiglass dome mounted top center on its fuselage for the Manual Tracker position. Rivet Ball holds the distinction of being "the very first KC-135 of any variant to perform a reconnaissance mission." It also holds the distinction of obtaining the very first photographic documentation of Soviet Multiple Reentry vehicle (MRV) testing on October 4, 1968. On January 13, 1969 Rivet Ball was destroyed in a landing accident at Shemya when it hydroplaned off the end of runway 28 with no fatalities.
RC-135S Cobra Ball[edit | edit source]
The RC-135S Cobra Ball is a measurement and signature intelligence MASINT collector equipped with special electro-optical instruments designed to observe ballistic missile flights at long range. The Cobra Ball monitors missile-associated signals and tracks missiles during boost and re-entry phases to provide reconnaissance for treaty verification and theater ballistic missile proliferation. The aircraft are extensively modified C-135Bs.
There are three aircraft in service and they are part of the 55th Wing, 45th Reconnaissance Squadron based at Offutt Air Force Base, Nebraska. Cobra Ball aircraft were originally assigned to Shemya and used to observe ballistic missile tests on the Kamchatka peninsula in conjunction with Cobra Dane and Cobra Judy. Two aircraft were converted for Cobra Ball in 1969 and following the loss of an aircraft in 1981 another aircraft was converted in 1983. The sole RC-135X was also converted into an RC-135S in the late 1990s to supplement the other aircraft.
Following the loss of one RC-135T aircraft, an EC-135B was modified in 1985 as a TC-135S for use as a training aircraft for the RC-135S crews to enable them to train with the different aerodynamic effects from standard aircraft. It did not carry any mission equipment.
RC-135T Rivet Dandy[edit | edit source]
KC-135T 55-3121 was modified to RC-135T Rivet Dandy configuration in 1971. It was used to supplement the RC-135C/D/M fleet, then in short supply due to ongoing upgrades requiring airframes to be out of service. It operated under the Burning Candy operational order. In 1973 the aircraft's SIGINT gear was removed and transferred to KC-135R 58-0126, resulting in 55-3121 assuming the role of trainer, a role which it fulfilled for the remainder of its life.
The sole Rivet Dandy RC-135T, 55-3121 had its reconnaissance gear removed in 1973, and it assumed the role of aircrew proficiency trainer. Externally it retained the 'hog nose' radome and some other external modifications, but the trapeze below the tail was removed, and no refueling boom was fitted and the aircraft had no operational reconnaissance role. In this configuration it operated variously with the 376th Strategic Wing at Kadena AB, Okinawa, the 305th AREFW at Grissom AFB, Indiana, and the 6th Strategic Wing at Eielson AFB, Alaska. In 1982 the aircraft was modified with Pratt & Whitney TF33-PW102 engines and other modifications common to the KC-135E tanker program, and returned to Eielson AFB. It crashed while on approach to Valdez Airport, Alaska on 25 February 1985 with the loss of three crew members, thus ending the career of arguably the most historically significant member of the C-135 family. The wreckage was not found until August 1985, six months after the accident.
RC-135U Combat Sent[edit | edit source]
The RC-135U Combat Sent is designed to collect technical intelligence on adversary radar emitter systems. Combat Sent data is collected to develop new or upgraded radar warning receivers, jammers, decoys, anti-radiation missiles, and training simulators.
Distinctly identified by the antennae arrays on the nose, tail, and wing tips, three RC-135C aircraft were converted to RC-135U (63-9792, 64-14847, & 64-14849) in the early 1970s and 63-9792 was converted to Rivet Joint, late 1978, and all aircraft are based at based at Offutt AFB, Nebraska. Minimum crew requirements are 2 pilots, 2 navigators, 3 systems engineers, 10 electronic warfare officers, and 6 area specialists.
RC-135V/W Rivet Joint[edit | edit source]
The RC-135V/W is the USAF's standard airborne SIGINT platform. Its sensor suite allows the mission crew to detect, identify and geolocate signals throughout the electromagnetic spectrum. The mission crew can then forward gathered information in a variety of formats to a wide range of consumers via Rivet Joint's extensive communications suite. The crew consists of the cockpit crew, electronic warfare officers, intelligence operators, and airborne systems maintenance personnel. All Rivet Joint airframe and mission systems modifications are performed by L-3 Communications in Greenville, Texas, under the oversight of the Air Force Materiel Command.
All RC-135s are assigned to Air Combat Command. The RC-135 is permanently based at Offutt Air Force Base, Nebraska., and operated by the 55th Wing, using various forward deployment locations worldwide. Under the "BIG SAFARI" program name, RC-135Vs were upgraded from the RC-135C "Big Team" configuration, itself a mission modified RC-135B (the first version delivered). RC-135Ws were originally delivered as C-135B transports, and most were modified from RC-135Ms. For many years, the RC-135V/W could be identified by the four large disc-capped MUCELS antennae forward, four somewhat smaller blade antennae aft and myriad of smaller underside antennae. Baseline 8 Rivet Joints (in the 2000s) introduced the first major change to the external RC-135V/W configuration replacing the MUCELS antennae with plain blade antenna. The configuration of smaller underside antennae was also changed significantly.
RC-135X Cobra Eye[edit | edit source]
The sole RC-135X Cobra Eye was converted during the mid-to-late-1980s from a C-135B Telemetry/Range Instrumented Aircraft, serial number 62-4128, with the mission of tracking ICBM reentry vehicles. In 1993, it was converted into an additional RC-135S Cobra Ball.
RC-135W Airseeker[edit | edit source]
The Airseeker is a SIGINT aircraft for the Royal Air Force (RAF) based on the Boeing RC-135 Rivet Joint aircraft. Three KC-135R aircraft are to be purchased and converted to RC-135W Rivet Joint standard. The cost per airframe is believed to be $330 million.
The Airseeker is to replace the RAF Nimrod R1 in the signal intelligence role. The Nimrod R1 was scheduled to be retired in March 2011 due to the cost of airframe maintenance and the cancellation of the Nimrod MRA4 upgrade programme due to escalating costs. However, due to the R1s involvement in Operation Ellamy its retirement was delayed until June 2011.
In January 2011 personnel from No. 51 Squadron RAF began training at Offutt for conversion to the RC-135. The conversion of three KC-135R airframes to RC-135W standard is to be undertaken by L3 Communications, who will also provide ongoing maintenance and upgrades under a long-term agreement.
The three airframes are former United States Air Force KC-135Rs, all of which first flew in 1964 but will be modified to the latest RC-135W standard before delivery. The three airframes on offer to the UK are the youngest KC-135s in the USAF fleet. The aircraft have approximately 23,200; 22,200 hours; and 23,200 flying hours respectively, as of September 2010. The first one will be rolled out for painting in January 2013 ahead of delivery in December 2013, and they are expected to remain in service until 2045.
Operators[edit | edit source]
Accidents[edit | edit source]
- On 13 January 1969, USAF RC-135S, 59-1491, called "Rivet Ball", was returning from an operational reconnaissance mission, when it landed at Shemya Air Force Base, AK in a snowstorm. The aircraft slid off the ice covered runway and plunged into a 40-foot ravine. Later "Ball" aircraft were equipped with thrust-reversers on their TF-33 turbofan engines, but this aircraft had J-57 turbojet engines without thrust-reverse capability. All of the eighteen crew members successfully evacuated the aircraft. The aircraft was written off as damaged beyond repair, but many components specific to the reconnaissance mission were salvaged for later use.
- On 5 June 1969, USAF RC-135E, 62-4137, called "Rivet Amber", departed Shemya Air Force Base, AK for a ferry flight to Eielson Air Force Base, AK. Although the purpose of this ferry flight is sometimes described as routine maintenance, in fact the aircraft had encountered severe turbulence on its previous operational mission and had been cleared for a one-time flight to be checked for possible structural damage at the main operating base. "Rivet Amber" was the heaviest -135 series aircraft ever built and was a highly sophisticated aircraft with a radar that weighed over 35,000 pounds and under each wing were specialized pods housing a heat-exchanger (right wing) and an additional electrical generator (left wing). During the flight all contact with 62-4137 was lost and the wreckage of the aircraft was never found.
- On 15 March 1981, USAF RC-135S, 61-2664, called "Cobra Ball," crashed on final approach in bad weather to Shemya Air Force Base, AK on a flight from Eielson Air Force Base, AK. The aircraft commander never established a proper glide path or descent rate on final and impacted the ground short of the runway. Of twenty-four occupants on board the aircraft, six were killed.
- On 25 February 1985, USAF RC-135T, 55-3121, operating out of Eielson AFB, AK was flying practice in very poor weather at the Valdez Municipal Airport, AK (VDZ). This one-time "Speed Light" aircraft had been re-engined with P&W TF-33 engines but was at this time only used for proficiency training in landings and air refueling, not for operational reconnaissance missions, but was sometimes called "Rivet Dandy." The first two approaches were uneventful, but the crew apparently became disoriented and the third Microwave Landing System (MLS) approach was commenced some four miles (6.4 km) north of the prescribed MLS inbound course. The crew of three (two pilots and a navigator) were killed when the aircraft flew into the side of a mountain. The approach procedure being attempted was certified for a de Havilland Canada DHC-7, STOL airplane. Both the glide slope and missed approach flight path were too steep for an RC-135 aircraft. The wreckage was not located until 2 August 1985.
