The connected at tips thing about the rotors is interesting tho. I'd reccomend it to any sub nut and someone who likes a game. I personally love the seawolf and even still play as one in the game "cold waters" which is a great sub game that you can play old and new subs in. Virginia is a new girl tho so I'm guessing it gets what goes with that. The seawolf without a doubt can outdive and who knows maybe outrun a Virginia but she was built for that purpose because Soviet subs dove deep and hauled ass and we needed a sub that could chase them in that arena so I'm betting, even tho it's classified, they fair well against some of the fastest and deepest divers the Russians have That said the Virginia's are newer and with age I've heard ships get noisy-er. There arent s bunch of them so I'm guessing they are upgraded often. I'd say the seawolfs we're a no holds barred build the best sub you can and their dollar amount shows that. So do the advancements to the latest Virginias make them more capable in total than the Seawolfs? I have no clue, and I would suspect that even if you knew all the classified details, the only way to find out would be in an exercise.Īlways fun listening to vepr get down on some real deal.sub talk. The Seawolf can likely go deeper and faster than the Virginia, although of course the figures are classified (it's certain the Seawolf cannot go 45 knots as some claim lol). There is also the matter of the potential logistical issues and age that the three Seawolfs face, but that's outside the scope of the question. By the end of the production run, the Virginias may even have a bow covered in a giant, conformal array of such hydrophones (that's speculation, but the Navy has been investigating such an array - CAVES - for several decades). I would guess, although I don't know for sure, that the LVA won't be installed on the Seawolfs for either weight or arrangement reasons. The LVA has vector hydrophones, which offer substantial improvements in sensitivity. The South Dakota and other Virginias will have the Large Vertical Array, which consists of two panels that wrap around the hull on either side. Most Virginias (and 688Is) have the WSQ-9 active intercept system, which probably cannot be mounted on the Seawolfs because the tips of their stern planes move. However, the Virginias have some sonars that the Seawolfs don't have. Thus the performance of the sensors that both classes have in common (passive bow array, towed arrays, WAA, LCCA) are probably comparable. The ARCI systems on both the Seawolf and Virginia classes are frequently upgraded, so I doubt that from the software side there is a large gap in capability. The other advancements have been to sonar. Since the baseline Virginia was designed to be as quiet as the Seawolf, it is not unreasonable to assume that machinery and propulsor advancements make the newest Virginias quieter than the Seawolfs were when they were new. The new rotors are seem to be mostly hybrid designs (meaning the blades are connected at their tips) and possibly composite. There have been a number of improved rotors for the propulsors. In particular, one of the components of the South Dakota Improvement Program - first tested on SSN 790, applied to Block V, and backfit on some older Virginias - is quieter machinery. In terms of the acoustic signature, there have been improvements throughout the production run of the Virginias. I will try to speculate as little as possible one can find much of the information below in SECNAV budgets.
