The solution adopted with the first batch of the County-class destroyers was to network them with ships carrying Type 984. Winkle was never built as it was quickly supplanted by Pixie, a very small unboosted warhead with an all-plutonium fissile core tested at Maralinga, which was, in turn, replaced by Gwen - an Anglicised version of the US W54 Gnat unboosted warhead of approximate yield 1/2 - 2 Kiloton (kt). , As experimental work progressed, the Ministry of Supply began forming an industry team to build production systems.

The Seaslug Mark 2 was based on the aborted Blue Slug programme to develop an anti-ship missile using the Seaslug missile and guidance system. First generation surface-to-air missile designed by Armstrong Whitworth for use by the Royal Navy.  Shortly after the new definition was produced, this project also moved to the RAE. Another common error is that the Mark-2 has semi-active guidance; actually, it was the same beam-rider than Mark-1, Articles needing clarification from January 2014, Articles with unsourced statements from September 2014, Articles incorporating text from Wikipedia, Cold War surface-to-air missiles of the United Kingdom, http://www.littlewars.org.uk/Seaslug/seaslug03.html, United Kingdom Aerospace and Weapon Projects, The Falkland Islands Conflict, 1982: Air Defense Of The Fleet, Seaslug: The most missile in the least space, "Seaslug - the Most Missile in the Least Space", https://military.wikia.org/wiki/Seaslug_(missile)?oldid=2935745, 4 solid fuel jettisoned boosters & liquid fuel, LOSBR (Line Of Sight, Beam Riding), in which the missile flew up a beam that tracked the target, CASWTD (Constant Angle of Sight With Terminal Dive), with the missile climbing at a low angle and then diving onto a low-altitude target. 10 Why deck’d with all that land and sea afford? In the immediately following period, a rationalized development program was laid out that called for the development of a surface-to-air missile for the Royal Navy that became Seaslug, a similar design for the British Army and Royal Air Force known as Red Heathen, and an air-to-air missile for the Air Force known as Red Hawk.
He was promoted to commander on 30 June 1955 and served as application commander responsible for bringing the navy's first surface-to-air missile, the Sea Slug, into service. 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.

After separation the main motor ignited to power the missile to the target.
First used in the NASAMS system which had initial operational capability in 1994/95. , When the deployment of the Seaslug was first being considered, three classes of custom missile-firing ships were considered.
It had a radio proximity fuze and 200 lb (91 kg) blast warhead. The handling arrangements were designed with a nuclear-war environment in mind and were therefore entirely under cover. This called for a significantly larger weapon than initially envisioned, capable of single-stage vertical launch, a warhead (and guidance) of 200 lb (91 kg) and an all-up weight of 1,800 lb (820 kg). Sea level LS H.M.S.
The firing of the first Sea Slug test missile from RFA Girdle Ness.
", Seaslug was a high-performance weapon in the 1960s, with a single-shot kill probability of 92%, although other sources give lower kill probabilities: 75% for the Mk 1 and 65% for the Mk 2. The Type 901 radar did produce three beams but it is the gathering beam that is separate; the guidance and target tracking beams are coaxial. , The designs were continually modified in order to find a suitable arrangement. It was unguided because the aircraft was too low to be acquired; the launch was intended to deter the pilot and to remove the exposed missile from the ship because it posed a fire hazard. The missile had four wrap-around booster motors which separated after launch. Results, if any, are unknown, but the impressive fireworks display associated with the launch sequence was something of a morale booster to the troops ashore. Sea Dart entered service in 1973 on the Type 82 destroyers and replaced Seaslug during the 1980s as the County-class destroyers were removed from service. Wikipedia, British first-generation, passive infrared homing air-to-air missile. The final warhead choice was Tony - a UK version of the W44 Tsetse boosted warhead, but all nuclear options for Seaslug were subsequently abandoned, and no nuclear-armed variant of Seaslug was ever deployed.
Control was by a modified Type 901M radar and it had an improved infra-red proximity fuze and a continuous-rod warhead with a smaller, 56 lb (25 kg), explosive charge (RDX-TNT) and an unfold diameter of about 70 feet (10 mm steel rods were used), The capabilities of the new Sea Slug Mk 2, an almost 2.5 ton missile, were much improved compared to the previous Mk 1. , The Navy found an unlikely ally in the Army, who were concerned that Red Heathen was too difficult to move to in a single stage and suggested that Seaslug might be the basis for a more immediate medium-range weapon that could be used both on land and sea.
