Operation Cockpit

Operation Cockpit was a bombing raid by aircraft from two Allied naval forces (Force 69 and Force 70) on 19 April 1944. The forces were made up of 22 warships, including two aircraft carriers, from the Royal Navy, Royal Australian Navy, French Navy, Royal Netherlands Navy, Royal New Zealand Navy, and United States Navy. The targets were Japanese port and oil facilities on Sabang Island (off the northern tip of Sumatra).

Background

A raid in the Sumatra area had been requested by United States as a distraction from their own operations on Hollandia (now Jayapura).[1] Somerville, the British commander, had selected Sabang for its location at the entrance to the Malacca Strait and its strategic installations, such as a radar station, port and airfields. At this time, Japanese forces in Burma were under pressure and suffering serious supply problems: the raid was expected to exacerbate these problems and thereby assist the British 14th Army. A further gain was the opportunity for Royal Navy and Fleet Air Arm crews to work with United States personnel and learn procedures needed for their subsequent deployment as the British Pacific Fleet.

The action had been made possible by the recent substantial increase in the destroyer strength needed to escort the task forces' capital ships.

The raid

The raid was launched at 5.30am on 19 April, with 17 Barracuda bombers and 13 Corsair fighters from HMS Illustrious and 29 Dauntless and Avenger bombers and 24 Hellcat fighters from USS Saratoga. It was highly successful, the Japanese were caught by surprise, there was no fighter opposition. Sabang harbour and the nearby Lho Nga airfield were bombed. Two merchant ships were hit and two Japanese destroyers and an escort ship strafed and set on fire. Thirty Japanese aircraft were destroyed on the airfield and a direct hit by a 1000-pound bomb set a large oil tank on fire. The power-station, barracks and wireless station were badly damaged. The submarine HMS Tactician reported large fires in the dockyard burning fiercely hours after the fleet had left the area.

Twelve US aircraft were hit by anti-aircraft fire; all but one made it back to Saratoga. The pilot of the one lost aircraft was recovered by Tactician, under fire.

Aftermath

The Japanese had been caught by surprise and the raid was a clear success - Somerville said that the Japanese "had been caught with their kimonos up".[2] The destruction of oil installations and shipping successfully contributed to the cessation of Japanese offensives in the Arakan.[3] There was a follow-up raid on Surabaya, Java in May 1944, named Operation Transom.
