Design

The Supermarine Stranraer was designed to meet the R.24/31 specifications, which were the same as the Saro London.

Prototype

The initial name of the prototype was the Singapore V. It was powered by two Bristol Pegasus IIIM radials and drove two bladed wooden propellers. It was first flown in mid-1935. It was renamed Stranraer soon after.

With the No 210 Squadron from October to November 1935 it underwent trials alongside the Saro London. Crews found it to be underpowered.
