The SZD-38 Jantar 1 (Amber) is a glider designed and produced in Poland from 1971.

Two prototypes of the SZD-37x Jantar were built (SP-2636 and SP-2637), using fibreglass reinforced plastic fuselage and tail-unit with an aluminium alloy tubular tail boom, SP-2636 was built with a 17.5m span wing and SP-2637 a 19m span wing.

The first flight of SP-2636 was carried out on 14 February 1972 and extensive testing carried out before the second prototype, SP-2637 (first flight 13 May 1972), was entered in the 1972 World Gliding Championships at VrŠac in Yugoslavia, taking the first place in the newly established 19m Class and the 3rd in the Open Class, flown by St.

The success of the SZD-37x prototypes in the World Championships was not repeated, due partly to shrinkage of the epoxy resin causing irregularities in the wing surfaces, and partly to the improved performance of the competing aircraft.

The SZD-38 broke seven Polish National records in 1973, but was soon out-classed in competitions.
