35th Bombardment Squadron The 35th Bombardment Squadron a United States Air Force unit . Its last assignment was with the 322d Bombardment Group , based at Phillips Field , Beltsville , Maryland . It was inactivated on 27 June 1949 . History . Established as a heavy bombardment group at Langley Field , Virginia in early 1940 as part of the buildup of United States forces after the breakout of World War II in Europe . Sixth Air Force . Was deployed to the Caribbean as part of the 1940 Destroyers for Bases Agreement with the British , departing Langley Field , on 26 October 1940 , and was assigned to Coolidge Field , Antigua in the British West Indies ( by way of Borinquen Field , Puerto Rico ) before the subsequent dispersal of its original personnel and equipment . It had been assigned as a subordinate element of the 25th Bombardment Group . In May 1942 , the unit was re designated as the 35th Bombardment Squadron ( Medium ) . On 31 October 1942 , the first of the confusing reassignments that have tainted the overall picture of USAAF activities in the Caribbean was instituted . At that time , the squadron inherited the personnel and equipment of the 430th Bombardment Squadron ( which had formerly been the 44th Reconnaissance Squadron ) . Additionally , the unit also got the personnel and equipment of the 99th Bombardment Squadron which had been based at Zandery Field , Surinam . Its personnel at Zandery becoming " A " and " B " Flight of the squadron , while the former 430th BS personnel and equipment became " C " and " D " Flights . In January 1943 , the Squadron Headquarters was moved from Coolidge Field back to Borinquen Field , Puerto Rico . " B " and " D " Flights of the 417th Bombardment Squadron ( Medium ) were reassigned to the squadron on 1 May 1943 . In addition , for short periods in January , March , July and August 1943 , while the German submarine warfare campaign was most critical , aircraft of the 80th Bombardment Squadron , 10th Bombardment Squadron , 8th Antisubmarine Squadron , 9th Antisubmarine Squadron and the Navy VB 130 were attached and / or operated intermingled with 35th BS aircraft . Additionally , during August 1943 , aircraft and crews of the 23d Antisubmarine Squadron were attached to the 35th . These reactions to the German threat were brought about , mainly between 19 and 30 July 1943 , by new and very bold tactics being displayed by the Axis U - boat s , now intent on fighting it out with patrolling aircraft on the surface . All of this makes it clear that the 35th BS was a prime element in the Allied anti - submarine campaign in the Caribbean . This realization was brought home on 1 August 1943 when operational and administrative control of the Squadron and its several detachments was transferred from the 25th Bombardment Group to Antilles Air Command . By 31 December 1943 the Navy had taken over the antisubmarine mission and the far - flung detachments were inactivated . By this time , the unit was little more than an Operational Training Unit . Although the Squadron was reassigned to Waller Field , Trinidad , nominally , on 7 February 1944 , as of 24 March this largely administrative transfer was ended and the Squadron was returned home to the United States . where the designation became that of a B - 25 Mitchell Operational Training Unit at Alamagardo Army Airfield , New Mexico The squadron was disbanded on 20 June 1944 . Cold War . Was activated as an Air Force Reserve squadron in July 1947 at Phillips Army Airfield , Maryland . May have operated some B - 25s , although that is undetermined . Inactivated due to budget restraints in June 1949 .
