Thunderbird (missile) : ウィキペディア英語版 | Thunderbird (missile)
The English Electric Thunderbird was a British surface-to-air missile produced for the British Army. Thunderbird was primarily intended to attack higher altitude targets at ranges up to approximately 30 miles, providing wide-area air defence for the Army in the field. AA guns were still used for lower altitude threats. Thunderbird entered service in 1959 and underwent a major mid-life upgrade to Thunderbird 2 in 1966, before being slowly phased out by 1977. Ex-Army Thunderbird I's were also operated by the Royal Saudi Air Force after 1967. Thunderbird had performance similar to other semi-portable missiles like the US MIM-23 Hawk and Soviet 2K11 Krug, although it pre-dates both of these systems and offered greater range. After its mid-life upgrades, which shared several components with the RAF's Bristol Bloodhound, Thunderbird featured a continuous-wave radar semi-active homing system that was highly resistant to Radar jamming and deception, and was able to track targets even at very low altitudes. Thunderbird was the Army's only heavy anti-aircraft missile. As systems like these made flight at medium and higher altitudes practically suicidal, nap-of-the-earth flying became the norm and even shorter-range, faster acting systems were needed. Thunderbird's role was taken over by the much smaller BAC Rapier as they became available. ==History==
