Comment: And you think these are a real threat? (Score 2) 167
If so you are kidding yourself. Never mind them not being armed with any anti-ship weapons (which are rather complicated to design, manufacture, and make work), they aren't facing up against their real military counterparts. These little narco-boats are not being hunted by US Navy subs and ASW ships. They are just dealing with the DEA and coast guard.
Also they have a much easier job of staying undetected than an attack sub. When you are just trying to get from point a to point b, subs can be fairly sneaky. However when they launch an attack, everyone knows where they are when said attack happens.
If they tried to interdict merchant shipping lanes and sink ships, they'd quickly find out they are playing in a league they can't deal with. To give you an idea:
A narco sub is 40 to 80 feet in length, made of fiberglass, wood, and maybe steel, has a diesel engine, can go about 6 knots, has a range of maybe 2000nm and generally isn't fully submersible. One of the few found that was (found before its maiden voyage I might add) could go about 300 feet under water. No design optimization for silent operation, no sonar, no torpedoes, weapons are only whatever the 3-6 crew have.
Against that would be the Virgina class attack subs. 377 feet long, made of reenforced steel and classified composites. Has a nuclear engine with unlimited range, and diesel backup, and go "more than 25 knots" the government won't say what its actual max speed is. Likewise it has demonstrated a public test dive to 800 feet, real max depth classified. It carries 12 tomahawk missiles, and has 4 torpedo tubes that can fire Mark 48 torpedoes (it carries 26 total of them) or harpoon anti-ship missiles. It has the best passive and active sonar systems the US has ever made, all the capabilities are classified. It has been designed to be as silent as possible and is supposed to be as quiet underway as a Seawolf tied to a pier (already a very quiet sub).
You really think there's any comparison?
You have to remember for all the chatter of a "war on drugs" it is really just an ineffectual police action. When one of these narco subs gets spotted, the crew scuttles it so as to not get caught with anything. The coast guard then rescues the crew. They are just (semi) stealthy drug transports.
If they were being used to interdict and sink shipping traffic, there would be a REAL war and these things wouldn't be looked for so their crews could be taken in to custody, they'd be blown the fuck up. Wouldn't just be the US on their ass either, though they would be the biggest threat, merchant ships are flagged from nations all over the world, they'd all be out for blood if they were getting blown up.
