L-29 Delfin Profile

The L-29 Delfin was a jet trainer developed in Czechoslovakia in the 1960s that won a competition to become the standard trainer for Warsaw Pact countries. Over 2,000 were supplied to the Soviet Union and 400 to Czechoslovakia, with others going to Eastern bloc allies. It was straightforward to fly, rugged, and served as both a primary and advanced combat trainer. While production ended in the 1970s, the L-29 has become a popular warbird in the US, UK, and elsewhere in recent decades, with around 50 still airworthy today.

PROFILE: Aero Vodochody L-29 Delfin


(Variants / Other Names: L-29A Delfin Akrobat)

HISTORY:
The prototype of the L-29 Delfin ("Dolphin") trainer, called the XL-29, first flew
in Czechoslovakia on 5 April 1959, powered by a Bristol Siddeley Viper
turbojet engine. The second prototype, first flown in July 1960, was powered
by the Czech-designed M701 engine, which was to become the standard
installation.

In 1961, the L-29 was entered in a competitive design evaluation to find a new
Warsaw pact basic/advanced jet trainer to replace the piston-engine trainer
fleet. The other competitors were the Russian Yakovlev Yak-30 and the Polish
TS-11 Iskra. The L-29 won and subsequently became the standard trainer in
all Eastern-bloc counties except Poland.

The first production Delfin rolled off the assembly line in April 1963, and
production continued for more than 11 years, a huge statement of its success.
More than 2,000 were eventually supplied to the Soviet air force, and 400
more to the Czech air force. Others were supplied to Bulgaria, East Germany,
Hungary and Romania.

Straightforward, rugged and easy to fly, the L-29 was ideal as both a primary
jet trainer and as an advanced combat/weapons trainer. The Delfin was later
exported to several other nations including Egypt and Indonesia. A small
number of a single-seat version, the L-29A Delfin Akrobat, was produced, but
it never caught on.

In recent years, the L-29 has become popular on the jet warbird market, mostly
in the USA, but also in England, Italy and South Africa.
