Blowpipe was developed as a shoulder-launched, man-portable SAM for the British Army. Blowpipe uses a separate acquisition package that clips onto the missile launcher, reducing the weight and complexity of the missile itself. Blowpipe can be mounted on vehicles and has also been mounted in a retractable mast on submarines, being termed"SLAM"
After initial boost, a Crake sustainer motor provides the thrust. Blowpipe is optically guided and has now been superceded by newer missiles such as Javelin and Starstreak.
