Improvement in the jet-engine design allowed Avro to make an impromptu come back after the
Bumblebee disaster with the Hawker Siddeley Orenda P.13 engine from its Canadian division. With the Avro Arrow becoming less and less a possibility, the British firm decided to buy it to create a cheap, fast, short-range interceptor that they could sell to the cash-stripped British military.
The plane that would become the Avro Bolt was designed to peak at over mach 2 and have a cruising speed of at least mach 1 with a combat range of 1000 km (620 miles). It was originally armed with only 6 ADEN 30mm cannons before adding attachment points under the wings for Fireflash radar-guided air-to-air missile. This led to the inclusion of a small radar cone to increase its size and capability.
Its short and stubby frame was supporting its triangular delta wings and cruciform tail plane, the cabin was a bubble canopy with a ejector seat. The test pilots that tried the prototype were mixed in their review; while over mach 1 it was incredibly maneuverable and had a good handling, at slower speed it was a difficult to handle due to the need of keeping an aggressive angle of attack to maintain lift despite the relatively big wings. Nonetheless, it was convened that it would only be an issue during take-off as its cruise speed was close to mach 1, so better training was the only thing that would be needed. One of the test pilot perfectly resumed the plane: "It's at first a mean little brute but give it time and it's a real swan."
With the Supermarine Swift being more and more a disappointment with many accidents and aerodynamic difficulties, it was decided to temporarily ground the Swift in 1955. This was the moment Avro waited and they capitalized on it, proposing the Avro Bolt as a possible replacement. While some in the government had though about phasing the Swift with Hawker Hunter, the fact that the Hunter was mainly a fighter-bomber, not optimized for interception, made them decide to accept the Bolt as a replacement for the Swift instead.
Quite cheap, their number would grow, as a light-weight, all weather interceptor, the Avro Bolt was exactly what the British government could ask. Quickly replacing the Swift, in 1957 it was the main British interceptor. In the same year it would get its first refit with the replacement of the Fireflash missiles by the Firestreak heat-seeking air-to-air missiles, they would adapt the heat detector in the missile pod to simplify the process and avoid touching too much to the plane brand new electronics.
While a success on the British isles, it would also become a success on the international scene as Avro began exporting the cheap interceptor to other countries. In 1958, after the failure of the 14 July Revolution, the Hashemite monarchy in both Iraq and Jordan strengthen their ties with the British government to modernize their state and that included the sale of modern military equipment. Avro sold 200 Bolt to Iraq in addition of trainers and 30 to Jordan. Kuweit would soon follow with a contract for 30 Bolt and 300 Firestreak missiles, Qatar right behind them for 20 Bolt and 100 Firestreak missiles. In 1959 South Africa would take command of 50 Bolt with trainers and additional spare parts, with an option to increase the number up to 150. This command would be interrupted in 1963 with the ban on the sale of military hardware as part of the British effort against Apartheid.
Most of the pilots would eventually grow to love the plane, despite the initial reactions being usually pretty negative due to the tricky take-off. One of the squadron that would be ubiquitous with the Avro Bolt would be the famed squadron 303, the still maintained Polish squadron. Threatened to disappear after WW2, the British decision to offer asylum to any Polish refugee quickly led to the repatriation of many of the families of the original pilots as well as many members of the Polish resistance and army. The RAF was quick to capitalize on this and with the cooperation of the Polish Government in Exile, still located in London, they maintained a steady stream of volunteer to man the unit. They took the task of protecting their surrogate home with the upmost serious and warmly welcomed the arrival of the Avro Bolt to replace the problematic Swift. Nicknamed "Garbus" or "Garby" by the Polish pilot, garbus meaning hunchback in Polish, probably due to the plane bulging near the canopy, the name would spread amongst the British pilot as well.
It would keep its role until 1969, due to the advancement in electronic and weaponry, the Bolt platform had reached its maximal potential and a only a total redraw would allow it to be modernized. The arrival of the American Sidewinder missiles, superior to even the newly equipped Redtop missile, notably required entirely different weapon platform. Despite this, it would stay in British service until 1973 as secondary interceptor and would keep being used by international client until 1988.
