My pension says otherwise.
DCNS doesn't exist, but if you knew anything about it you would know it is Naval Group.
It isn't that hard if you are in the general heading of the surface group. With Artemis getting positioning is much easier with a fire solution at 50km range.
1989 is the limit of your access to French technology and in sonars/marine engines you have yet to surpass it.
Soooo... You're a French pensioner who now lives in the US but used to live in China and had a gold-digging Chinese girlfriend? Yeah, that must be true... Who am I to stop the A-class performance.
Uggh please man. When the Scorpene was first put in the water, its manufacturer was DCNS. The Scorpenes being built in India where under a DCNS contract. Every Scorpene in active service today was constructed under the auspices of DCNS. Naval Group is a 2017 development. Its just a name son.
Yes, it isn't that hard to intercept a carrier task-force in a submerged conventional sub moving at 4-8kns. Armchair Admiral at his best.
Conventional subs are good for patrolling green-water/littorals and maritime choke-points. Your fantasies of non-AIP Scorpenes sinking entire Chinese Navy CBG's are just that. Fantasies.
So everything in the Chinese Navy is 1989 french tech?
Which one is the pre 1989 sonar Mr. Chini Expert? The Type 206 towed array sonar on pre 2013 Type 054A's or the Type 311 TAS on the newest Type 054A's, or the Type 064 communications sonar or the Type 066 communications sonar on the newest Type 054A's or the Type 307 bow sonar or the Type 707A acoustic field analyser or the Type 723 vessel surroundings monitoring sonar?
That is the composition of a Type 054A's sonar suite son. But you're here talking about "pre-1989 Thomsons". Willfully ignorant doesn't even begin to describe you.
