Sukhoi T-4 "Sotka" model in 1/72 scale of Amodel
Early in the
nineteen-sixties, the Soviet VVS commander came up with a requirement for
primarily a Soviet very high speed supersonic attack aircraft. Its envisaged
performance was a top speed of over MACH 3 , range of 6,000 km and a take-off
weight of 100,000 kg . Sukhoi came with a proposal, the T-4 with a delta
wing configuration with small canards, and it was approved that Sukhoi
went ahead, involving many other research organisations in the USSR. During
development, the relations were not very good between the Sukhoi Design
Bureau and the VVS Authorization Committee due to lack of resources, capacity
and many defects in many components.
The first "101"
prototype was ready not before the end of 1971 and it flew for the first
time on August 22, 1972. This prototype performed reasonably well and had
acceptable handling qualities. Work was started on some additional test
planes to test various technical components like avionics and weapons systems.
However, the whole project was stopped for very unclear political reasons
by the top of the Communist Party.
Design Top Speed:
over Mach 3
As usual for many large Amodel kits, it has a fiberglass main fuselage and centre wing with many sprues with about 100 "short run" plastic parts. The leading- and trailing edges are provided in plastic to get sharp edges.
All parts need
significant clean-up, but nothing that can not be done by a modeller with
some experience. Although the parts are not of the high quality of most
current injection moulded kits, you can make a very special and unusual
model. You will need a lot of filler and do sanding however. The panel
lines on most parts are inscribed.
part # 31 I replaced by bending a piece of acetate clear sheet to get a
better end-result to avoid using the separate unclear windows.
Also, the hatch
windows were not used, but rather Microscale Kristal Klear was used later
The side panels #77 + 78 needed considerable sanding to get a smooth result.
The engine exhaust pipes are a bit crude but can be used.
For the intakes,
it was decided to make some intake cover plates from plastic card, painted
The canards were assembled at the very last stage, so after the metal finish had been applied.
Next, a coat of ALCLAD II titanium was applied with some panels in steel.
Next, some panels were painted dark grey and black as indicated and after the few decals were applied, the overall model got a protective coat of gloss Johnson Future varnish.
The nose was set in place and fixed down with a drop of superglue
Adding some small details like pitot tubes from metal needles, the landing gear and doors completed the model.
The T-4 "Sotka" ....
The end-result is a very remarkable model in the 1/72 Soviet collection.
