Minsk-based Peleng has developed a new electro-optical (EO) sensor package as part of a wider upgrade programme for the Russian Air Force's Tu-22M3 'Backfire' strategic bombers.

The new system, designated ST-22-1, can be used as a bombardment sight over land and sea, automatically picking out and tracking targets.

ST-22-1 optics have four switchable fields-of-view (FOV) - wide (8°×6°), medium (4°×3°), narrow (2°×1.5°), and 2× narrow (1°×0.75°) - all independently stabilised in two plains (vertical and horizontal). According to the manufacturer, the narrow FOV setting can detect a tank-sized target out to 15 km with a 90% degree of accuracy.

The optics can be panned from -40° up to 70° and ±30° longitudinally, with a maximum rate of 30°/s and a minimum speed for line-of-sight target tracking of just 0.05°/s.
