Incendiary rocket 7.2-inch

It was used in anti-aircraft fire (Ref 9, p 55) 5-inch Incendiary Rocket, used at ranges of about 5,000 yds, was an effective weapon when fired from landing craft in amphibious operations. The rocket head was loaded with thermite or oil incendiary mixtures... 

In 1943 the CWS began to develop a 2.36-inch incendiary rocket for the bazooka. Chemists filled shells with various thermite and PT mixtures and tested them. The missiles were not stable ballistically, and the fuel would not always ignite upon impact. While these problems might eventually have been solved, there was another obstacle that proved insurmountable. The rocket cavity held so little filling that it was practically... 

The development of incendiary rockets for the Army proceeded slowly until the autumn of 1944, because none of the theaters or branches of the armed services set up a military requirement for the munition. Then a joint Army-Navy testing and experimental board asked for one hundred 7.2-inch incendiary rockets for trial. This became a joint project of the Ordnance Department and CWS, with the latter filling the rocket with incendiary fuel and fitting it for bursting and ignition. The rocket head held about twenty pounds of PT fuel, a quantity shown by test to be adequate for starting fires. This rocket was never standardized, but the CWS would have considered it satisfactory for use as a standard munition if the need for such a rocket had arisen. ...
