However, by 1956 a new Continual tests took place over the next four years using both the Seaslug needed height, range and bearing information for targets. Seaslug was intended to engage high-flying targets such as reconnaissance aircraft or bombers before they could launch stand-off weapons. Maximum altitude should be 55,000 ft, but 45,000 would be considered acceptable. In contrast, the American Terrier missile was somewhat shorter at 13 ft 6 in (4.11 m), but this required an additional tandem booster which took the overall length to 28 ft 6 in (8.69 m).In 1954, during another review of the Navy's future operations, consideration turned from a "hot war" against the Soviets to a series of "warm wars" in the The designs were continually modified in order to find a suitable arrangement.

Seaslug was a first-generation surface-to-air missile designed by Armstrong Whitworth (later part of the Hawker Siddeley group) for use by the Royal Navy. In 1949 this gave rise to the 'Project 502' group from industry, with The 29 July 1949 update of the Staff Target called for a maximum range of 30,000 yd (27 km) and a minimum of 5,000 yd (4.6 km). This was about 50% better than the contemporary US When the deployment of the Seaslug was first being considered, three classes of custom missile-firing ships were considered. During early testing, the design was further modified and renamed GPV, for General Purpose Test Vehicle.

They suggested the much longer ranged Red Heathen was more important in the short term. The booster motors were positioned at the front of the missile, but this unusual arrangement gave accelerationGuidance was by radar beam-riding, the beam to be provided by Type 901 fire-control radar. This is one of the final tests at the Woomera testing range in Australia, and used a radio controlled Meteor jet as a target. At that time it was believed that For this role, the densest possible storage was required, so the initial design of a single booster rocket at the base end of the missile, as in most contemporary designs, was abandoned in favour of four smaller boosters wrapped around the fuselage, giving shorter overall length of about 20 ft (6.1 m) without making the missile larger in diameter as the boosters fitted within the area of the guidance wings. It was, however, limited by the complicated handling arrangements and since each County class ship carried only a single fire-control radar only one target could be engaged at once, though two missiles could be fired against it. Later improvements meant that it could also be used against ships. Some of the County Class destroyers were sold to Chile for the Armstrong Whitworth Aircraft entstand 1912 als Flugzeugbauabteilung des Rüstungskonzerns Sir W.G.
The Armstrong Whitworth Sea Slug was the Royal Navy's first beam riding surface to air missile and was fitted to County Class destroyers, which were actually cruisers, but falsely identified by the Navy as politicians believed Cruisers were obsolescent. It was assumed the targets would "jink" at 1G, so the missile needed to maneuver at 4G at sea level and 2.5G at 40,000 ft. Additional requirements were the ability to switch between targets in 6 seconds.The designers ultimately selected a maximum range of 30,000 yards, which included 6,000 yd (5.5 km) of coasting after motor burn-out. There were 3 flight modes: A later updated pushed the range to 30,000–60,000 yd (27–55 km) against a 600 kn (1,100 km/h), later 650 kn (1,200 km/h), target.
Admiral Test firings of the GAP-based examples, now known as Rocket Test Vehicle 1, or RTV.1, demonstrated beam riding in October 1956. The firing of the first Sea Slug test missile from The County-class destroyers were specifically built to carry Sea Slug and its associated control equipment. It was only fitted to the Royal Navy's eight It was planned that Seaslug's medium-range role was to be supplanted by a very long-range missile known as In December 1944, GAP put out a Naval Staff Target for a new anti-aircraft weapon,A March 1945 report called for the first test launches of LOPGAP from converted In 1945 a new Guided Projectiles Establishment was set up under the Controller of Supplies (Air) and in 1946 development of all ongoing missile projects moved to the In a January 1947 Navy review, the program was given the name Seaslug.
Development made use of on an earlier programme by the Fairey Aviation Company known as \"LOPGAP\" (Liquid Oxygen / Petrol Guided Anti-aircraft Projectile), and a Victory Ship specially converted into prototype escort ship, RFA Girdle Ness, was procured. Sea Slug was intended to engage high-flying targets such as reconnaissance aircraft or bombers before they could launch stand-off weapons. If one of the boosters did not fire the thrust would be significantly off-axis, a possibility which was addressed by moving the boosters forward so their exhaust was near the centre of gravity of the missile, allowing the missile's small control surfaces to remain effective.
