The Land Mattress



The Land Mattress was an unfortunate moniker given to a fairly impressive experimental multiple rocket launcher developed by the US at the end of World War II. Developers began with the naval 5-inch shell, and mounted it on a 3-inch (76mm) rocket launcher mounted in a tube – the 60lb rocket or RP-3. It was actually first developed as a way to give cover to amphibious troops disembarking on a beachhead.


In 1944, when Allies were racing across Europe it was used. It could fire 4 rounds per second with arrange of over 7 kilometers. When Allies were crossing the Scheldt estuary over a thousand were fired on 6 hours.

  1. Sorry to have to point this out but the Land mattress was a British invention and was nothing to do with the Americans as you’ve incorrectly put. If you look at the photos you can clearly see that the troops are either British or Canadian (wore the same uniform). The Land Mattress was invented by Lt Colonel Michael Wardell who was a British officer who served during both World Wars. Hope that clears it up…
