in reverse tho, how far the Kilo can detect and identify the British carrier and for how long she trailed the British carrier group before being found.
How does conventional sub even trail a carrier group? Conventional subs travel at 6 to 8 knots with best acoustic stealth. Carrier groups cruise at at least 20+ knots.
This whole scenario is either made up, or entirely bogus.
Besides, why would PLAN even need to use a conventional sub on a British joke of a fleet? There are land based anti-ship ballistic missile and long range anti-ship missiles, long range air-launch hypersonic and supersonic missiles carried by bombers, long range subsonic steal missiles carried by J16 and JH7A2. Surface combatant like 055 carrying hundreds of YJ-18.
Anyone who has been on this forum long enough and is NOT intentionally irrational (refuse-to-be-informed) will see how bogus this whole thing is. British tabloid level of a farce.
