Abstract:

The 2.75 inch Automatic Rocket Launcher T-110-E2B No. 2 equipped with Tube No. 3, fired a total of 104 rounds of which 69 were T217 slugs and 35 were T132 practice rockets. Cyclic rates were recorded from 632 rounds per minute to 935 rounds per minute. The average muzzle velocity of the T132 practice rockets was 1200 fps, with an average peak of 2850 fps at 1050, and a burnt out velocity of 2500 fps still remaining at 2000. The majority of patterns taken at 1000 from the muzzle using T217 slug ammunition showed all shots within 3 mils of the center of impact area, however, patterns taken of T132 practice rockets at 1000, 2000, and 3000 showed up to 11 mils dispersion.
