The Royal Aircraft Establishment Larynx (from "Long Range Gun with Lynx engine") was an early British pilotless aircraft, to be used as a guided anti-ship weapon. Started in September 1925, it was an early cruise missile guided by an autopilot.[1]
The RAF began work on a true "flying bomb" in September 1925. Compared with the RAE 1921 Target missile, the Larynx (Long Range Gun with Lynx Engine) was smaller, heavier, and faster. In fact, a 200 hp (150 kW) Lynx IV engine gave the device a top speed of about 200 mph (322 km/h), making it faster than contemporary fighters.
