Laying on the ground below the centre person is the rocket body protection plug which is removed from the rocket body when installing a warhead, to the left on the ground is the fuse for the rocket which will be installed after the warhead is in place. Vehicles equipped with this weapon Vehicles equipped with this weaponĪircrews installing a warhead on a HVAR rocket. Often HVAR and Tiny Tim rockets were used together with F-84 jets loading out up to 24 HVAR rockets and two Tiny Tims for an astounding rocket weight of 5,800 lb (2,600 kg). It was demonstrated that pilots inexperienced with the HVAR had decreased chances of hitting their target whereas experienced pilots could utilise them with deadly and almost pinpoint accuracy. The 5 in HVAR rocket was able to penetrate 4 ft of reinforced concrete and could be effectively used at sinking transport ships, destroying pillboxes, ammunition dumps, tanks, and railroad locomotives. The ∆V (Delta 'Vee') for the new HVAR increased from 216 m/s to 420 m/s (1,400 ft/s), more than enough to provide the flat trajectory the designers and the military wanted. This rocket was outfitted with Ballistite for the propellant which had a greater specific impulse greater than the British, German or Soviet versions of rocket propellant.
Increasing the rocket motor's size allowed for the rocket to take on the 5 in diameter throughout the entire length of the rocket thereby increasing the propellant capacity from 8.5 lb to 23.9 lb. The rocket was a good size however, adaptations were needed to make it a faster rocket especially in a flatter trajectory, being fired from an external mount on an aircraft. The HVAR was developed as an improvement upon the 5-inch Forward Firing Aircraft Rocket (FFAR) which had the same size warhead, however, it also sported an underwhelming 3.25 in (8.3 cm) rocket motor. This rocket began production towards the end of World War II and saw action through the Korean War. The HVAR (High-Velocity Aircraft Rocket) was developed to be an American unguided rocket utilised for attacking ground targets from aircraft.
