A full 8 x 60lb HE rocket salvo fom a Typhoon was the same as a full broadside from a Leander light cruiser with 8 X 6 inch guns.Look at Rocket Projectile 3in. Carried a 60lb warhead or a 25lb solid shot. Typhoon carried at (possibly others). The 60lb occasionally pops up and has to be cleared by EOD.
