Notes on some units:
- HMS Swiftsure torpedo load in 1977 (And in the rest of UK SSNs) should be a mix of ASW Mk23 Grog (Only with ASW capability) and unguided straight-running anti-ship Mk 8 Mod 4 (Mk VIII****). For try to simulate this, HMS Swiftsure (Entry 6393, 80/1, armed only with Mk 24 Mod 1 Tigerfish) is replaced in this scenario by HMS Warspite with older torpedoes (Valiant-class, entry 6390 with Mk 24 Mod 1 Tigerfish AND Mk8).
- Mk 24 Mod 0 Tigerfish (Estimated PH=40%) with only ASW capability were introduced in 1980, and Mk 24 Mod 1 (Estimated PH=30%) adding limited anti-surface capabilities were introduced in 1979, and both were very defective (See Admiralty Trilogy's South Atlantic War supplement, by Andy Doty).
- In consequence, to figure 1977, Blue player SHOULD EMPLOY ONLY Mk VIII** torpedoes to sink the Soviet surface ships.
- Towed Sonar 2024 in UK submarines were of very limited availability even in 1982, less even in 1977 (Probably no UK submarine equipped with it in 1977), and were not convergence zone capable See Admiralty Trilogy's South Atlantic War supplement, by Andy Doty, and his very interesting notes on UK subs sonar variants).
- Previously to her 1/1979-3/1983 refit HMS Swiftsure should be equipped with Sonar 2001BC (in lieu of Sonar 2020) and clearly without towed Sonar 2024.
- Nimrod R.1/P were based at RAF Wyton from its introduction on 1974 to 1995 (From then rebased at RAF Waddington to its retirement on 2011), ASV.21 surface search radar was replaced by weather radar in 1980, and in-flight refuelling probe added 1982, just after South Atlantic War.
