Saro SR.53 и SR.177
<...>
Практически параллельно с работами по SR.53 компания «Saunders-Roe» вела разработку несколько большего по размерам самолета SR.177, который предполагалось использовать в качестве многоцелевого истребителя для ВВС. В то же время этим проектом заинтересовалось британское Адмиралтейство, заказавшее в 1956 году шесть предсерийных прототипов. Они должны были иметь усиленный планер, узлы крепления к катапульте и посадочный крюк. В качестве силовой установки предполагалось использовать ТРД de Havilland Gyron Junior тягой 3629 кг и ЖРД de Havilland Spectre 5A аналогичной тяги. Кроме того, интерес к самолету проявила и Западная Германия.
Программы SR.53 и SR.177 были закрыты после выхода «Белой книги» британского правительства 1957 года, провозгласившей переход на обеспечение ПВО страны с помощью ракет, а не пилотируемых самолетов.

Самолет SR.177 был дальнейшим развитием SR.53. К моменту закрытия программы был построен натурный макет, и началась постройка прототипа.

Air Pictorial 1958-03 / ??? - The Saunders-Roe S-R.177
Unless there is a sudden change of Government policy the S-R.177 will not be built, and it is to be regretted that this interesting design has been shelved owing to lack of funds and foreign orders. The history of the development of the 177 is in itself of interest, and it is published here by kind permission of Saunders-Roe.

LAST OF THE DEDICATED BOMBER-KILLERS: The OR.329/F.155 contenders
ISSUED BY THE Air Ministry in mid-1954, Operational Requirement 329 outlined what the Air Staff wanted from the next generation of interceptor aircraft, and Specification F.155 detailed how this requirement should be met. The demands of F.155 included the following:
- the ability to intercept an enemy bomber flying at Mach 1+ within 20min of target contact (approx 250 miles - 400km - from the UK);
- a service ceiling of at least 60,000ft (18,000m);
- the ability to carry armament of a mixture of infra-red homing and radar-guided missiles;
- a crew of two; pilot + weapons officer/navigator.
Thus the result would have to be a rapid-climbing Mach 2+ interceptor capable of carrying at least two collision-course missiles, and which would eventually replace the English Electric P.1B Lightning. Engine manufacturers also set about developing new powerplants for this new generation of fighters, including de Havilland (Gyron/Gyron Junior) and Rolls-Royce (RB.106).
Ten designs were put forward for F.155, but none proceeded beyond the design stage, the 1957 Defence White Paper sounding the death knell of the dedicated bomber-killer. The ten were:
Avro Canada CF-105 Arrow Added to F.155 towards the end of the process, the Canadian Arrow was essentially a stopgap to cover probable delays in the Fairey Delta 3 project (see below).
Avro 729 Little appears to be known about the Avro 729; it was described variously as a single-Gyron-powered all-weather fighter and a twin-engined canard design, as seen here.
Vickers-Armstrongs (Supermarine) Type 559 This canard design with a large air intake beneath the cockpit for its twin Gyrons, one atop another, as on the P.1, was to carry a pair of Red Hebe missiles on dorsal pylons. Deemed too radical
de Havilland D.H.117 Powered by a pair of Gyron Juniors and a D.H. Spectre booster rocket in the tail, the straight-winged D.H.117 was deemed not radical enough, and certainly not enough of an advance on the P.1B Lightning.
Fairey Delta 3 Based on research undertaken with the Delta 2 (F.D.2), Fairey submitted two designs to F.155; a large twin-Gyron-engined Red Hebe-carrying version that would meet the full spec, and a smaller, less ambitious single-engined version that would be easier to develop. The large version was selected by the MoS and Air Staff.
Armstrong Whitworth AW.169 With a pair of Gyron Juniors in nacelles fitted to a razor-thin straight trapezoidal wing, the T-tailed AW.169 would carry Blue Vestas on its wingtips.
English Electric P.8A much modified and larger Lightning fitted with Red Tops on its wingtips, this was considered insufficient advance on the P.1B.
Saunders-Roe P.187 A development of the company’s SR.53 and SR.177 mixed-power concepts, the P.187 was too big from the outset.
Hawker P.1103 This was to be powered by a single Gyron, with detachable rocket boosters mounted mid-wing and Red Hebes on its wingtips.Другие самолёты на фотографии: Armstrong Whitworth A.W.167 - Великобритания - 1955Armstrong Whitworth A.W.169 - Великобритания - 1958Avro Type 730 - Великобритания - 1957Avro Canada CF-105 Arrow - Канада - 1958De Havilland D.H.117 - Великобритания - 1958English Electric / BAC Lightning - Великобритания - 1957Fairey FD.2 - Великобритания - 1954Hawker P.1103 / P.1121 / P.1129 - Великобритания - 1957Vickers-Armstrongs (Supermarine) Type 559 - Великобритания - 1955
