Description

Gray overall. Green band on nose. Brown band just aft of green band. Gray tail struts.

Neither of these rockets had been put into production at the end of the war, although experiments had been finished on both of them. Both were designed as aircraft launched weapons for use against surface targets; type 5 No. 1 Mk 9 Model 1, against surfaced submarines, and type 3 No. 6 Mk 9 against landing craft and small ships.

These rockets are similar to the Mk 27 and Mk 28 rockets of comparable sizes, but both are somewhat heavier. Both carry high explosive loads, and type 5 No. 1 Mk 9 Model 1 has a semiarmor piercing nose.

Exact fuzing is unknown, but it is known that type 5 No. 1 Mk 9 Model 1 uses a fuze with a 0-2 second delay. Type 3 No. 6 Mk 9 is assumed to use an instantaneous fuze.

Both of these rockets are fin stabilized, and more closely resemble American aircraft launched rockets than any of the other Japanese rockets. However, their small propellant charges result in such low speed that their performance in no way compares with that of the American rockets.
