- casetă audio cu fir de oțel , numai pt uz militar (inscriptie ''air corps'' pe un comutator - folosita la aparatul RD-11B/GNQ-1, vezi alaturat); constructie solidă din Al, carcasa din metal feros, concepție total deosebita fata de oricare alt model de casetă : capul de înregistrare/redare este fixat pe șasiul interior al casetei, deci fiecare casetă are capul ei - asta servește la prelungirea vieții capetelor, supuse unei uzuri rapide din cauza vitezei mari a firului si elimina eventualii timpi de reparatie ; pt derulare înainte și înapoi s-au folosit contacte alunecătoare în legătura directa cu cele 2 role ; capacul din spatele casetei are contacte electrice (de la cap si de la role) ce vin în legătura cu cele din amplificatorul aparatului . Pt usurarea depanarii pe teren, carcasa are lipită pe interior schema legăturilor electrice; dimensiuni: 206 x 110 x 86 mm ; greutate - cca 1kg ; viteza firului - peste 40 cm/sec (apreciere personala in lipsa informatiilor exacte); pt. mai multe detalii, poza prezinta caseta fara carcasa; pt. comparatie cu alte 44 tipuri de casete audio - vezi tabelul din sectiunea ''despre casetofon'' .
