, SO —_ facilities, the air Fore ong capability in this area. This includes development and procurement of telemetering equipment, computing equipment such as analogue computers and tracking radars. 13. Development Testing of Weapons ComponentsandAssociated Equipment ae Aerodynanic Much of the aerodynamic testing of bomb shapes has been accom- plished for the AEC in WADC wind tunnels. Design work on optimum shapes of atomic weapons and of aircraft, guided missiles and rockets ie performed at WADC. Arnold Air Development Center will augment USAF wind tunnel facilities considerably when completed. Wind tunnel facilities of the NACA and of contractors also are available and in use by the Air Force. The WADC and the AF Flight Test Center do a great deal of nero- dynamic flight test work. b. Ballistics Special Weapons Command carries out bomb dropping programs to develop ballistics tables. The WADC budgets and contracts for the de- : velopment of ballistic data which is obtained by the Aberdeen Bombing “Mission. ce. The competence of the USAF in this area is clear. Environmental The Air Force has extensive facilities at WADC and at Air Proving ’ Proving Growid Conmand for conducting environment) testing in connection These facili- " with aircraft, guided missiles and associated equipment. - ties include capabilities for tropical, cold, altitude, humidity, fungus, vibratiion, and endurance types of testing. Cold weather testing of air- craft and major componer.ts is conducted annually in Alaska, Canade end During periodic maneuvers by $.7 snd eee at Mt.
