The Vickers-Armstrongs Valiant
was a British four-jet high-altitude bomber, once part of the Royal Air
Force's V bomber nuclear force in the 1950s and 1960s. The Valiant was
the first of the V bombers to become operational, and was followed by
the Handley Page Victor and the Avro Vulcan; it was noticeably less
advanced than its counterparts. The Valiant has the distinction of being
the only V bomber to drop live nuclear weapons. Beyond the nuclear deterrence role, the Valiant was also used by the RAF for other purposes, a number were converted to perform various support roles such as aerial refuelling tankers and aerial reconnaissance aircraft. Valiants were used for conventional bombing missions over Egypt for Operation Musketeer during the Suez Crisis of 1956. By late 1964 it was found that all variants of the Valiant showed premature fatiguing and inter-crystalline corrosion in wing spar attachment castings, traced to the use of a poorly understood aluminium alloy. Rather than proceeding with an expensive rebuilding program, the Valiant was formally retired in 1965. |

den 1950er und 1960er Jahren ein Teil der V-Atomstreitmacht der Royal Air
Force war. Der Valiant war der erste der V-Bomber, der in Betrieb genommen
wurde, ihm folgten der Handley Page Victor und der Avro Vulcan. Er war
deutlich weniger fortgeschritten als seine Gegenstücke. Die Valiant war der
einzige V-Bomber der eine Atomwaffen abwarf. |

|
On 8 February 1955, this first production Valiant was delivered to the RAF. A total of 108 Valiants would be manufactured, including the sole B.2 prototype. Valiants of 90 and 214 squadrons were used for air refuelling through the addition of a Hose Drum Unit (HDU) in the bomb bay, mounted on the same suspension units that were also used for bombs. The Valiant B.1 fleet was later switched to a low-level flight profile, after which fatigue due to increased turbulence was discovered and this ultimately led to the type's premature retirement. |
Am 8. Februar 1955 wurde diese erste Serienmaschinen an die RAF geliefert. Es wurden insgesamt 108 Valiants hergestellt, darunter der einzige B.2-Prototyp. Valiants der 90 und 214 Staffekn wurden für die Luftbetankung durch den Einbau einer Schlauch-Trommeleinheit (HDU) in der Bombenbucht verwendet, die auf denselben Aufhängungseinheiten montiert war, die auch für Bomben verwendet wurden. Die Valiant B.1 Flotte wurde später auf ein Low-Level-Flugprofil umgestellt, nach dem Ermüdungsriss durch erhöhte Turbulenzen entdeckt wurden welche letztlich zum vorzeitigen Ruhestand des Typs führte. |
