From the Anigrand website:
"In the late 1950s, the U.S. Navy started the Polaris program which was to arm submarines with ballistic missiles. The USSR quickly issued requirement to industries for an Anti-Submarine-Warfare system. A vehicle was initially seen as urgently needed to destroy Polaris-missile submarines. The Minister of Defense selected Bartini's floatplane design, and ordered Beriev OKB to build three prototypes. It was to be developed in three phases.
The VVA-14M1 was to be a technology test-bed with inflatable pontoons. The VVA-14M2 was to be more advanced with fly-by-wire flight controls. The third stage would be the VTOL vehicle fully equipped with armament. In 1972, the first prototype made its maiden flight as as aeroplane.
In 1974, the inflatable pontoons were installed but its expansion and retraction caused many problems. So later it was replaced by rigid pontoons, the fuselage was lengthened and a pair of starting engines were added. The program continued in 1974 but the engine resonance caused breakage of landing gears and rear control flaps. It never flew again and eventually drew to a close as Beriev was given higher-priority work with the A-40 and IL-78."
The model kit consists of 100 rsin casts parts with clar resin canopies and sharply printed decals. And as is Anigrand's way, the kit also includes three little 1/144 kits of other Soviet aircraft. We can't tell you, because Anigrand doesn't tell us! You can see some parts in the sprue shots, though.
