2-inch RP (original) (raw)

The 2-inch RP, short for Rocket Projectile, 2-inch, Number 1 Mark 1, was an unguided rocket weapon developed by the Royal Navy in the 1950s. It is generally similar to contemporary rockets like the SNEB and FFAR, although somewhat smaller. It is sometimes known as the RP-2 or RN, but most often referred to simply as the 2-inch.
