Powered by Soloviev turbofans of about 11,000 lb st (49 kN) each, the Geophysica is a version of the Myassischev M-17, from which it differs in having two engines, with enlarged lateral air intakes and a modified front fuselage with raised canopy line. The wing, with a span of 123 ft (37,5 m), and the tail unit appear to be unchanged from those of the M-17, which is powered by a 15,420 lb st (68,6 kN) Rybinsk (Kolisev) RD-36-51V engine.

The Model 230 is an updated version of the Bell 222, to be powered by Allison 250-C30-G2 turboshafts and available in wheeled or skid-gear versions.
