giving shorter overall length of about 20 ft (6.1 m). The boosters were positioned so they lay within the diameter defined by the missile's wings, so they did not make it any larger in diameter when stored. If one of the boosters did not fire the thrust would be significantly off-axis, a possibility which was later 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. 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).

accurately guiding Red Heathen at its desired 100,000 yd (91 km) maximum range. In September 1948 they agreed to develop Seaslug "as a matter of insurance", before further upgrading it in 1949 to "top priority". As a result of these changes, the program was seen as having two stages, Stage 1 would deliver missiles in the mid-1950s with roughly 20 miles (32 km) range with capability mostly against subsonic targets, and a Stage 2 of the early 1960s would have a greatly extended range on the order of 150 miles (240 km) and able to attack supersonic aircraft.

311: 844: 1200: 745:. A final series of tests at sea, which culminated in sixteen successful firings, finally cleared the missile for service in 1961. After more than 250 launches, the Seaslug Mark 1, also known as Guided Weapon System 1, or GWS.1, finally entered service in 1962 on County-class, each fitted with a single twin missile launcher and a complete weapon system with one fire control set and 30 missiles. The Seaslug-armed cruisers were cancelled in 1957. 1146: 684:, the new environment meant that air cover by carriers could not be guaranteed, and the need for air defence for task-force sized groups became the primary concern. A cut to carrier construction, capping the fleet at four, released funds for missile ship construction. In October 1954, a new design emerged that demanded the speed to keep up with a fleet in combat, have guns limited to self-defence, and carrying a single twin-missile launcher. 42: 1183: 946: 637:(27–55 km) against a 600 kn (1,100 km/h), later 650 kn (1,200 km/h), target. 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. 1246:

RN and RAF standards of the era counted "hits" under the NATO ADM 1/28039 standard "K15", meaning the target would be destroyed within 15 seconds of a hit. In contrast, US standards of the era listed any damage to the target as a hit. For this reason, UK missile "hit" probabilities are generally much

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 boosters gave a total of about 60 tons-force, with 186 kg (410 lb) fuel for each one (145 kg in the Mk 1), accelerating it to over Mach 2. When they separated because

The Chilean ships were later

pointed out it would be more useful to have a larger number of small ships with 10 to 20 missiles than one larger one, but attempts to design such a ship resulted in one with room for the weapons but not the crew needed to operate them.

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. This led to a very long design, as was the case for most contemporary designs, this was abandoned in favour of four smaller boosters wrapped around the fuselage,

In March 1948 a new report from the DRPC noted there was not enough manpower for all four projects, and put Seaslug at the bottom of the priority list, claiming air attack would be less likely than submarine in the event of war. They suggested the much longer ranged Red Heathen was more important in

When the deployment of the Seaslug was first being considered, three classes of custom missile-firing ships were considered. The Task Force Ship would be capable of 30 kn (56 km/h) and would tasked with fleet air defence. The Ocean Convoy Escort was a 17 kn (31 km/h) vessel that

design. Hit probability was estimated to be 40% at maximum range, so salvos of three missiles would be fired at once, demanding a three-place launcher. This was later reduced back to a twin-launcher when it was realized accessing the missile in the middle launcher would make maintenance difficult.

In December 1944, GAP put out a Naval Staff Target for a new anti-aircraft weapon, capable of attacking targets at altitudes up to 50,000 ft (15,000 m) and speeds of up to 700 mph (1,100 km/h). This project was briefly known as LOPGAP, short for "Liquid Oxygen and Petrol Guided

The Navy found an unlikely ally in the Army, who were concerned that Red Heathen was too difficult to move to in a single step and suggested that Seaslug might be the basis for a more immediate medium-range weapon that could be used both on land and sea. The DPRC also began to have concerns about

fighters. 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 first combat use in the surface-to-surface role was during a shore bombardment on 26 May, when

Test firings of the GAP-based examples, now known as Rocket Test Vehicle 1, or RTV.1, demonstrated beam riding in October 1956. The Navy had set a date of 1957 for a broad modernization of the fleet, so they desired Seaslug to be cleared for service in 1956. To this end, they accepted the use of

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). Maximum altitude should be 55,000 ft, but 45,000 would be considered acceptable. A later updated pushed the range to 30,000–60,000 yd

524:

Development continued as before but was significantly hampered by the post-war exodus of engineering talent. Shortly after the new definition was produced, this project also moved to the RAE. Efforts by the Navy to change the name from Seaslug to the more ominous-sounding "Triumph" failed.

523:

In a January 1947 Navy review, the program was given the name Seaslug. 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).
