Halverson Detachment

Detachment

HALPRO or the Halverson Detachement was a group of 23 B-24 Liberators originally destined to join the 10th Air Force in the China, Burma, India Theatre of operations.

Under the command of Colonel Harry Halverson the detachment was originally assigned to conduct raids on Japanese Home Islands. The detachment was to fly from Florida to China via Africa but the Japanese offensive in Chekiang, China in May 1942 disrupted this plan.

The Heavy Bomber HALPRO force was then tasked with disrupting German petroleum plants in support of the British in North Africa. HALPRO departed the United States on 22 May 1942, flying for Egypt via Sudan. The 4,000 mile journey meant that some of the aircraft were grounded on arrival in Egypt.

On 11 June 1942, 13 HALPRO B-24s carried out the first USAAF attack on Europe, when they bombed oil refineries in Ploesti, Roumania, while the raid had little impact, it proved the concept that Heavy bomber could carry out long-range attacks against defended targets.

The HALPRO Detachment ultimately remained in the Mediterranean theatre. on 17 July 1942, the detachment was redesignated the Hal Bomb Squadron. It ultimately formed 376th Bomb Group when it was constituted in October 1942.
