You surprise me at thenlow production Figures
I recall 15 to 20 years ago, reading an article in the sister magazine “Air International” about the Soviet Ekranoplans and the Caspian Sea Monster which certainly implied that more of these were made

KM – Korab’l Maket (Test Ship) – later changed to Kaspiiski Monstr after it had been nicknamed ‘Caspian Sea Monster’ by western journalists.

Only one built – despite it having about three different numbers painted on the side.

It had two configurations – eight ‘lift’ jets at the front and two ‘cruise’ engines on the fin, the cruise engines were later moved to a pylon over the cockpit.

Lun (Hen Harrier) missile-firing ekranoplan – only one built.

Spasatel (Rescuer) SAR variant based on Lun – only one built.

A-90 ‘Orlyonok’ (Sea Eagle) – five built, one crashed, 3 at Kaspiisk, one in Moscow.

There are dozens of smaller designs – with AquaGlide (a six seat ‘sporting’ ekranoplan) being the most successful….

Beriev are still showing models of a proposed ginormous freighter ekranoplan, the Be-2500 …

A model of Spasatel was on show at MAKS 09 – presumably trying to attract investment ??

…as was Orlyonok…..
