USE: |
|
High speed target for firing practice with automatic anti-aircraft weapons. |
|
OPERATIONS: |
|
The rocket consists of a motor, motor extension, nose, and three plywood fins. This rocket is very similar to the Navy TR, and is a direct copy of the British 3 inch U.P. pro-jectile. |
|
PROPELLANT: |
|
The propellant is a solvent-extruded double-base powder (40 percent nitrocellulose), extruded into cylindrical grains 5" long and 7/8" in diameter, with a 5/16" axial hole. The propelling charge is ignited by an electric squib assembled within the rocket. |
|
M2A1, FLARE, MODIFICATION: |
|
When a flare is added to the M2 rocket for anti-aircraft target practice at night, the resulting projectile is designated as the rocket, target, anti-aircraft 3.25", M2A1. The flare burns for 15 to 20 seconds from the beginning of flight. |
|
LAUNCHER: |
|
These rockets are launched from the Target Rocket Projector, M1. |
