href="/wiki/Television_guidance" title="Television guidance">television-guided</a> <a href="/wiki/Glide_bomb" title="Glide bomb">glide bombs</a> of the 1950s which was cancelled during development. A key role was as an <a href="/wiki/Anti-shipping_missile" class="mw-redirect" title="Anti-shipping missile">anti-shipping missile</a>, using its guidance system to attack the moving targets. It would also replace unguided bombs between 5,000 and 10,000 lb (2,300 and 4,500 kg) against point targets, or be equipped with a <a href="/wiki/Nuclear_warhead" class="mw-redirect" title="Nuclear warhead">nuclear warhead</a>. A smaller 1,000 lb (450 kg) version was also developed for testing. The name is a randomly assigned <a href="/wiki/Rainbow_code" class="mw-redirect" title="Rainbow code">rainbow code</a>. </p><p>The goal of the system was to allow the bomb to be guided to 100 yards (91 m) of its target after being dropped from a jet bomber flying at 50,000 ft (15,000 m) altitude. It could manoeuvre at up to 3.5G so that it could quickly be aimed after breaking through cloud cover as low as 10,000 ft (3,000 m). Nuclear-armed versions were primarily intended to provide the launching aircraft with some stand-off range and avoid overflying the target, gliding about 50,000 to 60,000 feet (9.5 to 11.4 mi; 15 to 18 km) from the launch point. In this role, guidance using <a href="/wiki/H2S_(radar)" title="H2S (radar)">H2S radar</a> instead of the television camera was considered. </p><p>Development was cancelled when it proved too large for a newer generation of jet-powered naval <a href="/wiki/Strike_aircraft" class="mw-redirect" title="Strike aircraft">strike aircraft</a> while the nuclear stand-off role went to the much longer ranged <a href="/wiki/Blue_Steel_(missile)" title="Blue Steel (missile)">Blue Steel</a>. The anti-ship role went to a series of weapons, all of which were cancelled, before finally emerging as another television guided weapon, <a href="/wiki/Martel_(missile)" title="Martel (missile)">Martel</a>. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Development">Development</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Blue_Boar_(bomb)&action=edit&section=1" title="Edit section: Development"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The low accuracy of bombing during <a href="/wiki/World_War_II" title="World War II">World War II</a> led most air forces to begin experiments with guidance systems. The only fully operational devices were the German <i><a href="/wiki/Luftwaffe" title="Luftwaffe">Luftwaffe</a>'</i>s <a href="/wiki/Glide_bomb" title="Glide bomb">glide bombs</a>, notably <a href="/wiki/Fritz-X" class="mw-redirect" title="Fritz-X">Fritz-X</a> which was used against the <a href="/wiki/Royal_Navy" title="Royal Navy">Royal Navy</a> with some success during 1943. The <a href="/wiki/USAAF" class="mw-redirect" title="USAAF">USAAF</a> also introduced similar systems late in the war, which saw limited use in Europe and in the Far East. In 1946, the UK <a href="/wiki/Air_Staff_(United_Kingdom)" title="Air Staff (United Kingdom)">Air Staff</a> published a report on the Control of Bombs which led to a November 1947 development proposal by the <a href="/wiki/Royal_Aircraft_Establishment" title="Royal Aircraft Establishment">Royal Aircraft Establishment</a> (RAE).<sup id="cite_ref-FOOTNOTEForbat201246_2-0" class="reference"><a href="#cite_note-FOOTNOTEForbat201246-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> Starting in March 1949, the RAE released a series of technical notes describing such a weapon.<sup id="cite_ref-FOOTNOTEForbat201246_2-1" class="reference"><a href="#cite_note-FOOTNOTEForbat201246-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p><p>A development contract was won by <a href="/wiki/Vickers" title="Vickers">Vickers</a> under Operational Requirement 1059. <a href="/wiki/Barnes_Wallis" title="Barnes Wallis">Barnes Wallis</a> began development under the <a href="/wiki/Rainbow_code" class="mw-redirect" title="Rainbow code">rainbow code</a> name "Blue Boar". Initial design reports suggested a single weapon system could carry between 5,000 and 10,000 lb (2,300 and 4,500 kg) bombs as their payload. It had to be able to manoeuvre at 3 to 3.5G at sea level in order to provide the required accuracy, but also making them extremely difficult to shoot down. For nighttime use, a second 5,000 lb (2,300 kg) bomb on the same guidance channels would follow three seconds behind the first, and ignite a series of flares once reaching 10,000 ft (3,000 m) altitude, providing illumination for the television camera. An even larger version, Special Blue Boar, could carry up to 20,000 lb (9,100 kg), as it was noted that a single larger bomb would be easier to guide than several smaller ones. This was intended for carriage on the emerging <a href="/wiki/V-bomber" class="mw-redirect" title="V-bomber">V-bomber</a> force. There was also consideration given to guiding these bombs with <a href="/wiki/H2S_radar" class="mw-redirect" title="H2S radar">H2S radar</a> for true blind bombing.<sup id="cite_ref-FOOTNOTEForbat201246_2-2" class="reference"><a href="#cite_note-FOOTNOTEForbat201246-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p><p>The design consisted of a cylindrical midsection carrying four large rectangular wings with control flaps at the end of each wing. The wings were stored within the bomb casing and forced outward on launch using air pressure from a small air bottle. An ogive nose cone carried the <a href="/wiki/EMI" title="EMI">EMI</a> television camera and fuse, while a small boat-tail rear section contained a stabilized antenna to send television imagery to the launch aircraft and receive commands from it. Using <a href="/wiki/Vacuum_tube" title="Vacuum tube">valve-based</a> electronics, most of the midsection of the bomb contained four large electronics boxes, with the warhead in front, just behind the nose section. The <a href="/wiki/Autopilot" title="Autopilot">autopilot</a> was from <a href="/wiki/Smiths_Group" title="Smiths Group">Smiths Aviation</a>, and the hydraulics powering the controls were from British Messier.

It was designed to fall at an angle of about 40 degrees above the horizon, and a <a href="/wiki/Gyroscopic" class="mw-redirect" title="Gyroscopic">gyroscopic</a> system was used to produce a "datum" spot in the television signal that represented that desired angle. The television had a square scanning pattern, but only the center was in sharp focus, representing a field of view about 55 degrees wide. On the receiver television, a crosshair was used by the bomb aimer to keep the target aligned with the bomb's line-of-sight. The controls were designed to allow the bomb to be put on target within six seconds of breaking through clouds at 10,000 ft altitude.<sup id="cite_ref-FOOTNOTEForbat201250_4-0" class="reference"><a href="#cite_note-FOOTNOTEForbat201250-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> This was designed to provide a <a href="/wiki/Circular_error_probable" title="Circular error probable">circular error probable</a> of 100 yards (91 m) when dropped from 50,000 ft altitude.<sup id="cite_ref-FOOTNOTEForbat201252_5-0" class="reference"><a href="#cite_note-FOOTNOTEForbat201252-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p><p>EMI carried out a number of tests of the television system against the town of <a href="/wiki/Westbury,_Wiltshire" title="Westbury, Wiltshire">Westbury, Wiltshire</a> as a sample target. This started with normal aerial photography that was optically degraded to what they expected the television signal to look like at night when illuminated by flares.
