The DC-3 revolutionized air travel to an extent only surpassed by the advent of the jet aircraft. What made the DC-3 particularly special was the degree of safety it provided. Thanks to the DC-3 and its reputation for strength and reliability, in 1937 air travel insurance finally became available for the general public.

Eight decades after its first debut, the DC-3 is still flying, a tribute to the solidity of its brilliant design, and it will likely continue to fly for a long time.

The Van Speijk class frigates were equipped with Dutch electronics/sensors. The British Leander design was chosen to enable rapid construction to replace elderly escorts for ASW duties and NATO patrol. The ships were thoroughly modernised in the late 1970's. Between 1986-1990 all six were transferred to the Indonesian Navy.
