I mean, I know that attack subs need some sophistication but at the same time there's the Avatar. That's not light, insophisticated or inexpensive by any stretch.
And you don't need SSNs to give convoys a hard time--there exist modern classes of diesel-electric or air-independent propulsion subs that have sneaked up on the Enterprise battlegroup. (Now if only I can remember where I saw that...)
I do see the point re:shipyards, though. Hmm.
I think there were stories about a British diesel submarine managing to get
Enterprise in her sights for long enough to 'sink' her on a fleet exercise, but I can't recall the exact details.
I know that in the RIMPAC 98 fleet exercises
HMAS Onslow (an Australian
Oberon submarine built in the 1970s) managed to get within three hundred metres of the fleet carrier
Carl Vinson and 'sink' her.
So yeah, relatively primitive subs can be quite dangerous to main-line combat warships, let alone merchant ships in convoys. The problem, as has been pointed out, is that even relatively small submarines like the
Oberon class I mentioned above (displacing roughly two thousand tons compared to eight thousand for an
Arleigh Burke class destroyer or four thousand for an
Oliver Hazard Perry class frigate) require extensive shipyard facilities to produce, as we've seen with the effort to build the shipyards for our
Rapier-class hydrofoils. NOD normally operates deep in the Yellow or Red Zones so not only would they have to worry about protecting any shipyards from GDI retaliation (which would be even harder as we clear away orbital debris and can put up more recon and comms satellites) but also from the encroachment of Tiberium.
You'd really think they'd have frigates and destroyers... Those are extremely basic and it'd take incredible political stupidity for them to just not exist. Like, "No one other than Redmond Boyle ever made a decision involving naval procurement" stupid.
On the other hand, they may be relying on legacy world navy ships for that, stuff that dates back to the '90s and the time when GDI military equipment was recognizable real world stuff, or ships built to similar designs and only slightly newer... Stuff that's completely obsolete in the face of post-Tib War II Nod technology like cloaking.
That I could easily believe- GDI relying heavily on escort combatants built in the 1990s, 2000s, and maybe 2010s, having focused more recent shipbuilding on capital ships alone, and having suffered greatly for it as the escort combatants get cut to ribbons by Nod ambushes using cloaked weapons platforms that their old radar systems can't track and things like that.
I agree with you, Simon. Building battleships and carriers in realistic numbers simply does not provide enough numbers to fulfil the roles of a modern navy. Most of the action in Command and Conquer is on land, with ships being used either to deploy troops in amphibious assaults (a Landing Ship Dock is shown deploying hovercraft to land troops on a beach in the first mission of the first game) or to provide fire support from guns or from aircraft. This might be why there is so much emphasis on battleships and carriers in GDI, especially if NOD does not field large naval forces of its own. So with most of GDI's naval efforts focused on big ships like the battleships and aircraft carriers it makes sense that they'd just produce more of the lighter ships that were already being built, rather than coming up with new designs. So as the first C&C game was set in the early 1990s GDI is probably still churning out
Perry and
Broadsword frigates designed in the 1970s, and
[Arleigh Burke destroyers designed in the 1980s, with attempts to update their technology which have failed to keep them effective against current NOD forces.
@Ithillid How big are the
Rapier-class hydrofoils we are currently building? Are they as big as the modern destroyers mentioned above, in the several thousand ton range? Or are they more along the lines of small patrol gunboats and missile boats, like the Soviet Osa class or the US Pegasus class?
