In Memoriam

Klaas Willem Jonker
(Wilko)
† April 30, 2018

On Monday 30 April 2018, Wilko Jonker died after a long illness at the age of 58. He leaves behind a wife and two children. The Dutch military aviation and plastic modeling were his hobby and on this website he shared all the knowledge he has collected over the years. His hobby has been able to distract him from the persistent disease in his body until the last week of his life. The contacts with other hobbyists were a major support for him.

This website will be maintained by different people for as long as possible, so that other enthusiasts can continue to benefit from extensive content.

Westland Wasp

History

The Westland Wasp was, just as the Westland Scout, the result of the same development program P.531 of Saunders-Roe or SaRo. Both types originate somehow from the Saunders-Roe Skeeter, a light helicopter, which was a development of the Cierva Aurogiro. In 1959 SaRo merged in Westland Aircraft.

The Skeeter was equipped with a piston engine, whereas the Scout/Wasp were equipped with a turbine engine.

Development

Because of the ongoing submarine mid fifties threat the Royal Navy made a list of requirements, MATCH (=Manned Torpedo Carrying Helicopter). This aircraft had to attack submarines with torpedoes.

The SaRo P.531 was developed based on these requirements and it made its maiden flight on July 20, 1958.

The P.531 was intensively tested by the Royal Navy and also several types of under carriage were tested. In September 1961 Westland received an order for two aircraft,designated Sea Scout. The Sea Scout made it's first flight at the end of October 1961.

Soon an definite order for 98 aircraft followed and also orders were received from abroad, e.g. the Netherlands, Brasilia and Indonesia. A total of 133 examples was built.

The Wasp was in essence the same as the Westland Scout, which was developed for the Royal Army. main difference was the four wheeled under carriage, which could be used to manoeuvre on a flight deck. The rotor blades were constructed in such a way they could press the Wasp on the flight deck, so the aircraft could be anchored to the deck.,.

Further extra fuel tanks in tail and under the floor were added; tail and rotor blades were fold-able  and a hoist was available at starboard and load could be carried with a sling. Three passengers could be transported and for emergencies a stretcher could be carried.

Later inflatable floats were added and also provisions to carry and launch the Nord SS11 and also the SS12 missile.
