Some get retired early due to new drilling tech...or the fact oil companies have rather large budgets...They are already set up for machine shops, a helipad, barracks, etc. <br />For example, one place in the international waters of the Persian gulf could support true littoral craft such as Mark VI patrol boat. A modified MkVI could be fielded with ASW equipment similar to that of an SH-60 but be much more economical in terms of endurance, or given mine-hunting UAV for a (admittedly limited) MCM capability (But still better than the mythical LCS module). The mother-station would have Anti-air capability (from SeaRAM to VLS depending on the size) and house the crews and provide repair for the boats. A dozen smaller boats could do the job of an LCS over a wider area while providing smaller, multiple targets, economical operation, and the added benefit of multiple first commands for junior officers to cut their teeth on. <br /> You could tow one within pirate prone areas to support PBs doing escort or even CG cutters and patrol boats. When the threat subsides, you can tow it elsewhere.

(And it had better have substantial onboard medical facilities too, for obvious reasons.)

We already have those for the LCS, they are the Combat Logistics Force ships (e.g. T-AO, T-AKE, T-AOE)."<br /><br />I've never heard any suggestion that the T-X's are a dedicated or formal part of the LCS operations concept. Of course, those vessels are available for any need, by any ship, so your suggestion isn't completely incorrect, however, as Scott points out, for any worthwhile operation by the LCS (or a group of them) we would have to dedicate one or more T-X's to their exclusive use. That leads not only to the protection/risk issue that Scott raises but also to the lost opportunity cost of dedicating a very valuable logistics support vessel to very marginal combat vessels. Those logistics vessels could be much better used elsewhere.<br /><br />The premise of the post was that we should be thinking about using motherships as more than simple supply ships. We should be looking for motherships and groups that can contribute combat capabilities by mutually enhancing each other's capabilties. The point of the post was that we should expand our concept of a mothership. Simply tasking a T-X to tag along with an LCS doesn't fit that premise even if we wanted to accept the risk and opportunity cost.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-24201993219039294312014-12-26T09:39:50.492-08:002014-12-26T09:39:50.492-08:00====================

We already have those for the LCS, they are the Combat Logistics Force ships (e.g. T-AO, T-AKE, T-AOE)." <br />====================<br /><br />Just as a point of interest, Sean Stackley says that the LCS doesn't need help from an AEGIS cruiser (i.e., a Burke or a Tico) to safely operate within a high threat battlespace.<br /><br />On the other hand, an LCS running continuously at high speeds will need to be refueled every 24 hours. If that must be done by a Combat Logistics Force ship -- T-AO, T-AKE, T-AOE etc. -- where will the refueling operation take place? <br /><br />If the refueling operation must take place inside a high-threat operations area, then a DDG must be present to protect the LCS and the CFL ships while the refueling operation is in progress, is that not so? <br /><br />And if no DDG is present, the LCS must be refueled outside the high threat areas within the battlespace, meaning that the LCS must spend a good portion of its forward-deployed assignment transiting between its battle zone forward station and its rear area refueling station. <br /><br />In the latter case, the faster the LCS goes in making its transit to and from the rear area CLF refueling station, the more fuel it burns in doing so. <br /><br />It is not hard to foresee a circumstance where the CLF ships are too vulnerable to be placed too well forward inside the battlespace, and the only available option is to refuel the LCS from one or more DDG's.

The Chinese anti-ship IRBM, the so called "carrier killer", is useless because there is no effective means of targeting at the 1000+ mile range of the missile. So, just because a missile has a given range doesn't mean that it can be effectively employed from that range.<br /><br />Take the case of a sub with a long range cruise missile. It's highly unlikely that a sub could, on its own, generate targeting data at the max range of the missile (presumably 100+ miles). If the sub has to close to within 5 or 10 or 20 or 50 miles to generate valid target data, then the helos have their chance.<br /><br />Of course, with today's networking, the sub may be able to launch from max range using target data from another platform. In that case, the issue for the ASW group becomes one of denying the targeting platform.<br /><br />Going further, the mothership can carry many more defensive AAW missiles (ESSM and RAM) than a single sub can carry cruise missiles. So, again, just because a sub might be able to shoot at a mothership doesn't mean that the concept is not viable. With an adequate med/short range defense the mothership would stand a good chance of survival. I would also remind you about the historical data on anti-ship missile attacks. The success rate is very poor even against ships without active defenses (SAMs and guns). We've covered this in previous posts.<br /><br />So, I would suggest that your caution is valid and noteworthy but does not rule out ASW mothership concepts. If the sub with a missile was that powerful and effective, surface fleets would be obsolete - to be fair, there are those believe exactly that!<br /><br />For what it's worth, the V-22 has been evaluated for an ASW role and rejected by the Navy. They didn't publish the specific reasons why but I assume it's because of the extremely poor performance while in the slow speed helo mode. A longer range helo might well be a viable solution.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-43075774087184149992014-12-24T07:37:43.957-08:002014-12-24T07:37:43.957-08:00The concept has merit.

The problem I see is that you're concentrating all of your short-legged SH-60's (ROA of 100 nm) in one basket. <br /><br />Given the proliferation of ultra quiet AIP subs with long-ranged cruise missiles, they can shoot the mother-ship well outside of its patrol radius.<br /><br />I think to really make the concept effective, they will need:<br />1. A much longer-ranged ASW helicopter or;<br />2. Lots of small ships to act as lilly-pads.<br /><br />Option 1 could be V-22 ASW or MH-XX.
