    Hedgehog

    Does anyone know if the British Navy used the US 7.2-INCH rockets (hedgehog)? I am wondering what their designation for them was.

    Thanks,

    Hedgehog was not a rocket. It was a spigot mortar.

    Minenaz16,

    The propelling charge on the drawing in your post is 260gr (16.8 grams).

    I think that would be too small for a rocket.

    from the first post the US rocket was a Hedgehog warhead with a new rocket motor. I have not seen any information about the rocket in British use, only the mortar round

    Minenaz16 is looking at the same one I am. The US Hedgehog was an anti-sub Rocket. However you can see the MK number on the second picture, what was the NO used?

    In OP 1664: https://maritime.org/doc/ordnance/pg176.htm
    You can see the chart that brought on this question. I know the US and UK shared items throughout the war. In this chart you see us calling the 7.2 inch rocket NO 208, 211, 212, 213, 216 and 217. I would think these were UK designations that we were using at the time, but I cannot verify this.

    Hedgehog - Spigot Mortar,
    Mouse Trap - Rocket, 'Hedgehog' warhead on a rocket motor. As far as I'm aware, the Royal Navy never used 'Mouse Trap'
