Progress demands resources, and they are often harder to find than a genius solution. A suitable platform was required to test a new modification of front-line bomber engines, but the Me.410 was as precious as air on the field for intercepting enemy Flying Fortresses. The solution was simple and elegant. The air force had sufficient numbers of the Fw 189 Uhu – a famous reconnaissance aircraft – and its configuration, light design and simple installation process for new power train parts and mechanisms made the aircraft a perfect test platform.

Any new vehicle of an enemy or ally often becomes not only a soldier in your army or a target for testing out your weapons, but also an object of deep study with a view to absorbing the experience of engineers from other countries. The M3 Lee was no exception. Test data obtained in the testing grounds are sure to help Britain make its new military vehicle prototypes even better, and the Grant modification, stripped down to the screws, has again taken on its original form, receiving protection from the deadly sands of the desert and an upgraded turret. The M3 Grant is ready to serve the greater good in real battles on the side of Britain.

The original Grumman F7F Tigercat is the first US twin-engine carrier-borne fighter – it stands out for its very high maximum speed and powerful frontal armament. But better is always good. A third modification of this aircraft has arrived from the testing ground, equipped with a new power train. The engineers haven’t failed to take advantage of this, and it became possible to mount additional launchers with rockets, including the large anti-ship Tiny Tim rockets!
