Roumur is that Soviets backed Argentinians and Brits with Satellite imagery. That position of Belgrano was given to Brits and Position of fleet to Argentinians.
Kronos please stop with the stupidity. Are you seriously suggesting that the Russians supplied the UK with sat imagery? If you have read your rumours correctly then you would have seen that it was claimed that the Russians suppled Argentina with sat imagery.
The Belgrano along with the Argentine carrier had been trailed for days using the SSNs. All very basic stuff. Both Argentine battle groups. Group North led by the carrier and group south led by the Belgrano had to emit using both sonar and radar. Easily detectable and trackable. The SSNs were shadowing the Argentine surface fleet for weeks beforehand. The Argentine had no option but to withdraw their surface fleet as the RN SSN threat was far too potent.
