The Rolls-Royce RB.93 Soar, also given the Ministry of Supply designation RSr., was a small, expendable British axial-flow turbojet intended for cruise missile use and built by Rolls-Royce Limited in the 1950s and 1960s. Like all the company's gas turbine engines it was named after a British river, in this case, the River Soar.
