Rockwell Tank Breaker - portable anti-tank missile system (ATGM), developed by Rockwell International Corporation in the framework of the Tank Breaker program in 1978-1984. The infrared homing head (IR seeker) to the rocket was developed as an independent product, the development was started earlier as part of a preliminary contract concluded by the US Army Missile Forces Administration with Rockwell International and Hughes Aircraft before the official announcement of the competition for the creation of a new generation ATGM [1] . According to company representatives, the GOS IC in their embodiment allowed the shooter to solve fire tasks with equal efficiency both when shooting at ground targets and at low-flying low-speed air targets (helicopters in hover mode, as well as landing or taking off helicopter propellers).

Rockwell International's hybrid focal plane array receiver consisted of three elements: [4]
- Photoelectric Detector Array (PDA);
- CCD - multiplexer (Si CCD multiplexer);
- Galvanized indium columns connecting the detector array with a silicide multiplexer electromechanically.
Electrons generated as a result of photon absorption are accumulated by plane matrices of pn junctions . The resulting photocurrent from each individual element of the detector array is transferred to the CCD through separate indium connectors . Introductory cells of the CCD perform the function of suppressing the background, thereby reducing the intensity of the background flow and expanding the dynamic range of the CCD [4] . Rockwell International’s CCDs used a background suppression method that implements two technological principles simultaneously: sliding (skimming) and charge separation [5] . In the period from 1978 to 1980, Rockwell International engineers paid special attention to the development of a clearly defined and reproducible sequence for processing the infrared signal during its passage through the passivated semiconductor material of the receivers, as well as increasing their performance [6] .
