Operation Eagle Claw

Operation Eagle Claw, known as Operation Tabas () in Iran, was a United States Armed Forces operation ordered by U.S. President Jimmy Carter to attempt to end the Iran hostage crisis by rescuing 52 embassy staff held captive at the Embassy of the United States, Tehran on 24 April 1980.
The operation, one of Delta Force's first, encountered many obstacles and failures and was subsequently aborted. Eight helicopters were sent to the first staging area called "Desert One", but only five arrived in operational condition. One had encountered hydraulic problems, another was caught in a sand storm, and the third showed signs of a cracked rotor blade. During the operational planning, it was decided that the mission would be aborted if fewer than six helicopters remained operational, despite only four being absolutely necessary. In a move that is still discussed in military circles, the field commanders advised President Carter to abort the mission, which he did.
As the U.S. forces prepared to withdraw from "Desert One," one of the remaining helicopters crashed into a transport aircraft that contained both servicemen and jet fuel. The resulting fire destroyed both aircraft and killed eight servicemen.
In the context of the Iranian Revolution, Iran's new leader, Ayatollah Ruhollah Khomeini, stated that the mission had been stopped by an act of God ("angels of God") who had foiled the U.S. mission in order to protect Iran and his new conservative theocratic government. In turn, Carter blamed his loss in the 1980 U.S. presidential election mainly on his failure to secure the release of the hostages.
Motivation for military intervention.
On 4 November 1979, fifty-two American diplomats and citizens were taken hostage in the United States Embassy in Tehran, Iran by a group of Iranian college students belonging to the Muslim Student Followers of the Imam's Line, avid supporters of the Iranian Revolution. American President Jimmy Carter called the hostage-taking an act of "blackmail" and the hostages "victims of terrorism and anarchy." but in Iran it was widely seen as an act against the U.S. and its influence in Iran, including its perceived attempts to undermine the Iranian Revolution and its longstanding support of the Shah of Iran, Mohammad Reza Pahlavi, who was overthrown in 1979.
The crisis had reached a climax after diplomatic negotiations failed to secure the release of the hostages. Facing elections and with little to show from negotiations, the Carter government ordered the State Department to sever diplomatic relations with Iran on 7 April 1980. Cyrus Vance, the United States Secretary of State, had argued against a push by National Security Advisor Zbigniew Brzezinski for a military solution to the crisis. Vance left Washington on Thursday 10 April for a long weekend vacation in Florida. On Friday 11, Brzezinski held a newly scheduled meeting of the National Security Council where he insisted that it was time to "lance the boil", and Carter said it was "time for us to bring our hostages home". It was during this Security Council meeting of 11 April, that Carter confirmed that he had authorised the mission. He did however continue to entertain the planning for a concurrent punitive air-strike, but this was finally rejected on 23 April, one day prior to the commencement of the mission. The rescue mission was code named "Operation Eagle Claw".
Planning and preparation.
Planning for a possible rescue mission began on November 6, two days after the hostages were taken.
Army Major General James B. Vaught was appointed as Joint Task Force commander and was to be forward-based at Wadi Kena in Egypt, reporting directly to the President. In turn, he had two field commanders: USAF Colonel James H. Kyle as the field commander for aviation and U.S. Army Delta Force Colonel Charlie Beckwith as ground forces field commander.
The ambitious plan was to be based on the use of elements from all four branches of the U.S. military: army, navy, air force, and marines. The concept was based on an operation whereby helicopters and C-130 aircraft, following different routes, would rendezvous on a salt flat (code-named "Desert One") 200 miles (320 km) southeast of Tehran. Here the helicopters would refuel from the C-130s and pick up the combat troops who had flown in on the C-130 transports. The helicopters would then transport the troops to a mountain location ("Desert Two") closer to Tehran from which the actual rescue raid would be launched into the city the following night. The operation was further to be supported by an in-country CIA team. On completion of the raid, hostages were to be shepherded to a captured Tehran airport from which they were to be flown to Egypt.
On 31 March, anticipating the need for military action, a U.S. Air Force Combat Controller, Major John T. Carney Jr., was flown in a Twin Otter to "Desert One" by covert CIA operatives Jim Rhyne and Claude "Bud" McBroom for a clandestine survey and reconnaissance of the proposed landing areas for the helicopters and C-130s. Carney successfully surveyed the airstrip, installed remotely operated infrared lights and a strobe to outline a landing pattern for the pilots. He also took soil samples to determine the load-bearing properties of the desert surface. At the time of the survey, the salt-flat floor was hard-packed sand, but in the ensuing three weeks an ankle-deep layer of powdery sand had been deposited by sandstorms.
The Tehran CIA Special Activities Division in-country paramilitary team, led by retired U.S. Army Special Forces officer Richard J. Meadows, had two assignments: to obtain information about the hostages and the embassy grounds and to transport the rescue team from "Desert Two" to the embassy grounds in pre-staged vehicles.
"Desert One" was in the South Khorasan Province, in the Dasht-e Lut desert near Tabas () while "Desert Two" was located 50 miles (80 km) short of Tehran at .
Assault teams.
The ground forces consisted of 93 Delta soldiers to assault the embassy and a 13-man special forces assault team from Detachment "A" Berlin Brigade to assault the Ministry of Foreign Affairs where three further hostages were being held. A third group of 12 Rangers were to act as the roadblock team at the "Desert One" landing area. Rangers were also tasked with taking and holding the Manzariyeh Air Base near Tehran to provide the springboard for escape from Iran. In addition, the CIA had prepared an in-country team of 15 Iranian and American Persian-speakers, most of whom would act as truck drivers.
Ingress.
The complex plan required that on the first night, three USAF EC-130Es (Call signs: "Republic 4", "5", and "6") carrying the logistical supplies and three MC-130E Combat Talons (Call signs: "Dragon 1", "2", and "3") carrying Delta Force and Ranger troops (132 assault and security troops in total) would depart the island of Masirah, off the coast of Oman for "Desert One," a flight of over 1,000 miles (1600 km). They would be refuelled by Air Force KC-135 tankers en route. "Desert One" would be secured by a protection force and once secured, a refueling area would be established for the helicopters with approximately 6,000 US gallons (22,700 L) of jet fuel being made available from collapsible fuel bladders carried in the C-130s.
Eight United States Navy (USN) RH-53D Sea Stallion (Call signs: "Bluebeard 1 – 8") helicopters were positioned aboard , 60 miles off the coast of Iran. The helicopters would fly to "Desert One", refuel, load up the Delta Force and part of the Ranger teams, and then fly 260 miles (420 km) further to "Desert Two." Because it would be close to morning, the helicopters and ground forces would hide during the day at "Desert Two". The rescue operation would take place the second night.
Rescue raid.
First, CIA agents who were already inside Iran would bring trucks they had sourced to "Desert Two". Together, the CIA officers and ground forces would then drive from "Desert Two" into Tehran. This assault team would assault the embassy and Foreign Affairs building, eliminate the guards, and rescue the hostages, with air support from Air Force AC-130 gunships flying from "Desert One." The hostages and rescue team would then rendezvous with the helicopters which had flown from "Desert Two" to the nearby Amjadieh Stadium where the rescue teams and the freed hostages would board the helicopters.
Egress.
In parallel to the rescue, an Army Ranger company would capture the abandoned Manzariyeh Air Base near Tehran to allow two C-141 Starlifters flying from Saudi Arabia to arrive. With the Rangers holding the airport, the helicopters would bring everyone from the stadium to the Manzariyeh airbase, where the C-141s would fly everyone back to an airbase in Egypt. The eight helicopters would be destroyed before departure.
Protection and support.
Protection for the operation was to be provided by Carrier Air Wing Eight (CVW-8) operating from "Nimitz" and CVW-14 operating from . For this operation, the aircraft bore special invasion stripe identification on their right wings. This was necessary to distinguish support aircraft from Iranian F-14 and F-4 aircraft purchased by Iran from the US in the time of the Shah. CVW-14 Marine F-4Ns were marked with a red (VMFA-323) or yellow (VMFA-531) stripe enclosed by two black stripes while CVW-14 attack aircraft (A-7s and A-6s) had an orange stripe enclosed by two black stripes.
The mission.
Only the delivery of the soldiers, equipment and fuel by the C-130 aircraft went according to plan. MC-130 "Dragon 1" landed at "Desert One" at 22:45 local time. The landing was made under blacked-out conditions using the improvised infrared landing light system installed by Carney on the airstrip, visible only through night vision goggles. The heavily loaded "Dragon 1" required four passes to determine that there were no obstructions on the airstrip and to align with the runway. "Dragon 1" off-loaded the road-watch teams in Jeeps and a USAF Combat Control Team (CCT) to establish a parallel landing zone north of the dirt road and to set out TACAN beacons to guide in the helicopters.
Soon after the first crews landed and began securing "Desert One", a civilian Iranian bus with a driver and 43 passengers was stopped while traveling on the road, which now served as the runway for the aircraft. The bus was forced to halt by the Rangers and the passengers were detained aboard "Republic 3". Minutes after the bus had been stopped, the Rangers in the road-watch team observed a fuel tanker truck, ignoring their orders to halt, bearing down on them. The truck, apparently smuggling fuel, was blown up by the Army Ranger roadblock team using a shoulder-fired rocket as it tried to escape the site. The truck's passenger was killed, but the driver managed to escape in an accompanying pickup truck. As the tanker truck was thought to be engaged in clandestine smuggling, the driver was not considered to pose a security threat to the mission. However, the resulting fire illuminated the nighttime landscape for many miles around, and actually provided a visual guide to "Desert One" for the disoriented incoming helicopters.
Two hours into the flight, RH-53D "Bluebeard 6" made an emergency landing in the desert when a sensor indicated a cracked rotor blade. Its crew was picked up by "Bluebeard 8" and the aircraft was abandoned in the desert. The remaining helicopters ran into an unexpected weather phenomenon known as a "haboob" (an enormous, nearly opaque cloud of fine dust). "Bluebeard 5" flew into the haboob, but abandoned the mission and returned to the "Nimitz" when electrical problems disabled flight instruments and flying without visual references proved impossible. The remaining six helicopters reached "Desert One", 50 to 90 minutes behind schedule. "Bluebeard 2" arrived last at "Desert One" at 01:00 with a malfunctioning secondary hydraulic system, leaving only one hydraulic system to control the aircraft.
With only five fully serviceable helicopters now remaining to transport the men and equipment to "Desert Two" (minimum of six aircraft was the planned mission's abort threshold), the various commanders reached a stalemate. Senior helicopter pilot Seiffert refused to use unsafe "Bluebeard 2" on the mission, while Beckwith (field commander for ground forces) refused to consider reducing his trained rescue team's size. Kyle (the field aviation commander), therefore, recommended to Vaught that the mission be aborted. The recommendation was passed on by satellite radio up to the President. After two and a half hours on the ground, the presidential abort confirmation was received.
Collision and fire.
Fuel consumption calculations showed that the extra 90 minutes idling on the ground waiting for the abort confirmation order had made fuel critical for one of the EC-130s. When it became clear that only six helicopters would arrive at "Desert One", Kyle had authorized the EC-130s to transfer 1,000 US gallons (3,800 L) from the bladders to their own main fuel tanks, but "Republic 4" had already expended all of its bladder fuel refueling three of the helicopters and had none to transfer. To make it to the air tanker refueling track without running out of fuel, it had to leave immediately and was already loaded with part of the Delta team. In addition, RH-53D "Bluebeard 4" needed additional fuel, requiring it to be moved to the opposite side of the road.
To accomplish both actions, "Bluebeard 3" piloted by Maj. James Schaefer had to be moved from directly behind the EC-130. The aircraft could not be moved by ground taxi and had to be moved by hover taxi (flying a short distance at low speed and altitude). A Combat Controller attempted to direct the manoeuvre from in front of the aircraft but was blasted by desert sand churned up by the rotor. The Controller attempted to back away, which led "Bluebeard 3" pilot to mistakenly perceive that his craft was drifting backward (engulfed in a dust cloud, the pilot only had the Controller as a point of reference) and thus attempted to "correct" this situation by applying forward stick to maintain the same distance from the rearward moving marshaller. The RH-53D struck the EC-130's vertical stabilizer with its main rotor and crashed into the EC-130's wing root.
In the ensuing explosion and fire, eight servicemen died: five of the fourteen USAF aircrew in the EC-130, and three of the five USMC aircrew in the RH-53D, with only the helicopter's pilot and co-pilot (both badly burned) surviving. After the crash, it was decided to abandon the helicopters and during the frantic evacuation to the EC-130s by the helicopter crews, unsuccessful attempts were made to retrieve their classified mission documents and destroy the aircraft. The helicopter crews boarded the EC-130s. Five RH-53D aircraft were left behind at Desert One mostly intact, some damaged by shrapnel. They could not be destroyed, because they were loaded with ammunition and any fire or explosion would have endangered the C-130s.
The EC-130s carried the remaining forces back to the intermediate airfield at Masirah Island, where two C-141 medical evacuation aircraft from the staging base at Wadi Abu Shihat, Egypt picked up the injured personnel, helicopter crews, Rangers and Delta Force members, and returned to Wadi Kena. The injured were then transported to Landstuhl Army Regional Medical Center in Germany. The following day, after learning about the events at Desert One from the local Iranian news, the Tehran CIA team quietly left Iran, with the Iranians unaware of their presence.
Aftermath.
The White House announced the failed rescue operation at 01:00 a.m. the following day (25 April 1980). Iranian Army investigators found nine bodies, eight Americans, and one Iranian civilian. The American bodies were later returned to the United States and buried at various locations across the country. The 44 Iranian civilians captured on the bus were released and subsequently gave eyewitness accounts of the operation.
Casualties.
The eight servicemen who died included three Marines (Sgt. John D. Harvey, of Roanoke, Virginia; Cpl. George N. Holmes Jr., of Pine Bluff, Arkansas; Staff Sgt. Dewey Johnson, of Dublin, Georgia) and five Air Force personnel (Maj. Richard L. Bakke, of Long Beach, California; Maj. Harold L. Lewis Jr., of Fort Walton Beach, Florida; Tech. Sgt. Joel C. Mayo, of Harrisville, Michigan; Capt. Lyn D. McIntosh, of Valdosta, Georgia; Capt. Charles T. McMillan of Corryton, Tennessee). On 25 April 1980, Major General Robert M. Bond read a message from President Jimmy Carter at a memorial service commemorating them in Niceville, Florida. A memorial honoring them was erected in the Arlington National Cemetery and Carter attended a memorial service there with the families on 9 May. Three of the servicemen who died – Maj. Richard Bakke, Maj. Harold Lewis Jr., and Sgt. Joel Mayo – were buried in the Arlington National Cemetery in a grave marked by a common headstone, located about 25 feet from the group memorial. In addition, five servicemen were injured, including USMC Majors Jim Schaefer, pilot, and Les Petty, co-pilot.
After the termination of the operation and the abandonment of equipment by the infiltration team, the Iranians became aware of the landings as well as the subsequent accident and firefight. Mohammad Montazer al-Qaim, Commander of the Yazd Iranian Revolutionary Guards Corps (IRGC) went to the scene to investigate reports from locals. At the same time, without knowing of the investigation activities of the IRGC, the Iranian Air Force conducted two observation flights over the incident area. During the first flight, two F-14s flew over the abandoned US equipment and the flight requested permission to fire on the equipment. This was refused by the Iranian command. The next day, Iranian Air Force F-4 fighter jets patrolling the area thought that the American helicopters were about to fly and they fired at the remaining American equipment, killing Mohammad Montazer al-Qaim.
Political consequences.
President Carter continued to attempt to secure the hostages' release before his presidency's end. On 20 January 1981, minutes after Carter's term ended, the 52 US captives held in Iran were released, ending the 444-day Iran hostage crisis. US Secretary of State Cyrus R. Vance, believing that the operation would not work and would only endanger the lives of the hostages, opted to resign, regardless of whether the mission was successful or not. His resignation was confirmed several days later.
Ruhollah Khomeini condemned Jimmy Carter, and in a speech after the incident, credited God with throwing sand to protect Iran. He said:
The embassy hostages were subsequently scattered across Iran to preclude any second rescue attempt and were released on 20 January 1981, minutes after Ronald Reagan had taken the oath of office after winning the election against Carter.
Investigation and recommendations.
Retired Chief of Naval Operations Admiral James L. Holloway III led the official investigation in 1980 into the causes of the operation's failure on behalf of the Joint Chiefs of Staff. The Holloway Report primarily cited deficiencies in mission planning, command and control, and inter-service operability, and provided a catalyst to reorganize the Department of Defense.
The various services' failure to cohesively work together prompted the establishment of a new multi-service organization several years later. The United States Special Operations Command (USSOCOM) became operational on 16 April 1987. Each service now has its own special operations forces under USSOCOM's overall control.
The lack of well-trained Army helicopter pilots who were capable of the low-level night flying needed for modern special operations missions prompted the creation of the 160th Special Operations Aviation Regiment (SOAR) ("Night Stalkers"). In addition to the 160th SOAR's creation, the US Defense Department now trains many military helicopter pilots in low-level penetration, aerial refueling and use of night-vision goggles.
In addition to the formal report, various reasons for the mission failure have been argued, with most analysts agreeing that an excessively complex plan, poor operational planning, flawed command structure, lack of adequate pilot training and poor weather conditions were all contributing factors and combined to doom the operation.
Commemoration.
United States.
The official Operation Eagle Claw Memorial is at Arlington National Cemetery and is described by cemetery literature as:
Iran.
The incident is considered as a US defeat and is commemorated annually in Tabas where government officials, religious leaders and people gather and display wreckage of the American planes and helicopters from the incident. A mosque called "gratitude mosque" was built at the crash site. On the road from Ashkezar to Tabas, at the location of "Desert One" there are several remnants of the operation, including wreckage and mock-ups of the RH-53D helicopters.
An Iranian air-defense system is named Tabas, in commemoration of the crash site. At the old Tehran Airport, there is the shell of a RH-53D airframe on display.
Second rescue plan.
Shortly after the first mission failed, planning for a second rescue mission was authorized under the name "Project Honey Badger". Plans and exercises were conducted, but the manpower and aircraft requirements grew to involve nearly a battalion of troops, more than fifty aircraft, and such contingencies as transporting a 12-ton bulldozer to rapidly clear a blocked runway. Even though numerous rehearsal exercises were successful, the helicopters' failure during the first attempt resulted in the development of a subsequent concept involving only fixed-wing STOL aircraft capable of flying from the US to Iran using aerial refueling, then returning to land on an aircraft carrier for medical treatment of wounded.
The concept called "Operation Credible Sport", was developed but never implemented. It called for a modified Hercules, the YMC-130H, outfitted with rocket thrusters fore and aft to allow an extremely short landing and take-off in Amjadieh Stadium. Three aircraft were modified under a rushed secret program. The first fully modified aircraft crashed during a demonstration at Duke Field at Eglin Air Force Base on 29 October 1980, when its landing braking rockets were fired too soon. The misfire caused a hard touchdown that tore off the starboard wing and started a fire. All onboard survived without injury. The impending change of administration in the White House forced this project's abandonment.
