DARPA's Defiant uncrewed vessel gets Caterpillar engine. Will begin sea trials soon.

The 210-metric ton MUSV-class ship is expected to be the first of its kind with maximum performance, reliability, and maintenance efficiency while still carrying significant payload at tactically useful ranges. The Navy plans to use it as a missile-laden drone boat. DARPA plans to deploy and maintain very large fleets of unmanned surface vessels that can serve as partners, across the globe, for the larger crewed combatants of the US Navy.

    I wonder what they'll use as the eyes and ears of this thing. It will have to know what it's launching against after all, unless the plan is to datalink into the missiles post launch. That would still require manned vessels be close to the enemy though, so I suspect there'll be a sensor platform variant

      We have several soundbites and glittering generalities but nothing concrete that I know of. Some thinking from pre-ukraine sea war will likely be discarded.

      This article has a couple hints. "Perception systems," daisy-chaining of vessels, and some other things.

      I don't think it does.
      It can just receive some orders and a data packet from a satellite link, upload the data packet to the missile, then fire that missile.

        The question isn't the how you moron there are two options and I outlined them, uploading while onboard using the boat's datalink and uploading to the missile directly post-launch, it's about where you're gonna get the data to upload into the missile.

        Burkes, Constellations, etc.

        That's what I'm referring to by "manned systems". I doubt it because it still means you're endangering your big expensive systems with lots of trained personnel onboard. This would do best paired with a USV sensor platform.

        That's a battle management system, you still need the sensors actually feed it data

          And those are literally on every surface ship, fixed wing asset, sats, or scattered on the ground. That is the purpose of the system: bring all the various sensors into one common program that can then be used by just about everything.

            Yes, but if you need targeting data from a manned ship then this doesn't exactly remove the risk from the manned ship. I find it unlikely that you can get real-time targeting data from a satellite at the exact right time and place to launch your weapons and any aerial drone is going to have a far harder time getting close enough for its sensors to provide targeting data. You don't need sub-shiplength levels of accuracy since you've got onboard terminal guidance, sure, but you still need to sling the missiles in the general vicinity of a moving and potentially maneuvering target, so you need a real-time track. I'm asking what the plan is to attain that track and if it minimizes the risk to valuable personnel and larger manned platforms you utter buffoon. I know what a BMS is you moron.

              It could be an F-35 or an AWACS, it doesn't NEED to be a destroyer or similar sized target.

                AWACS likely can't provide that targeting data with sufficient precision (remember, deviations in angle at a long range are magnified) and the F-35 one once again runs into the issue of bringing a very expensive system with a very expensive to train specialist into harms way, especially when they're going to be emitting, defeating the point of stealth.

                A low(er) cost USV that can get closer to the enemy with a small physical footprint, making it hard to actually hit on the open sea, would be a much more effective platform, and I'm wondering if that's a thing they're also working on, similar to Anduril's (previously Blue Forces) Fury, which is an unmanned aerial sensor platform.

                Holy shit, you are moronic. I'm not wasting any more time spoon-feeding you.

                You have not spoonfed me jack shit, I am perfectly aware of what a BMS is, and I am aware of IBCS. None of your posts are about the original question, which is regarding whether or not there was a sensor platform being developed to pair with this thing so your USV can engage targets while your expensive platforms sit far away acting as C&C platforms, which has been the general direction the US has been moving towards, most notably with the F-35. If you have nothing to add to the conversation frick off.

        OP

        Will be interesting to see how the space force side of JADC2 will integrate with whatever the naval variant of this BMS will be called.

        I'm also very curious about naval elaborations on northrop's recent success in scaling link16 down for tactical tablets in a meshnet without a central server. Now that we have that and SDA's confirmation that they fixed the teething issues with link16 to/from space, things can get real stupid and fun.

          > In February 2024 the Air Force's Brig. Gen. Luke Cropsey warned that phase two of Combined JADC2, which was supposed to go forward in 2024 is not starting because Continuing Resolutions (CRs) do not fund new program spending —full Congressional budget approval for FY2024 is required for Combined JADC2 to go forward in 2024.

          really starting to hate republicans for this shit, just because you don't get your way doesn't mean you should grind the military budget to a standstill for half a decade or more. This shit WILL have long term consequences.

              It did, but still likely not in time to do phase 2 in 2024, it'll probably slip a year.

              Tons of other programs that eventually got their FY24 funding had to delay shit ~5+ months which is going to have long term impacts, especially when this money was supposed to go towards long-lead production items which will just snowball delays later on.

            The current GOP is at the mercy of a radical minority that are arguably RINOs taking advantage of the chaos and ambiguity caused by the inflamed populism in the voter base to advance their personal agendas at any cost. The old guard is all about defense spending, but the GOP doesn't have institutional control over its members the way the DNC does.

      this implies that it would need a central "carrier" mothership or in this specific case a tender for replenishment for fuel, maybe ammo, and perhaps light repairs.

        Same. I suppose it's also important to note that there might not be any emissions nonsense on the military versions, they might eliminate it under national security auth.
        That fricker in the bottom left though? The C7.1?
        Presumably that's the "next gen" version of the C7, which is based on the 3126.
        I would rather get pegged than own anything with a C7 in it ever again. They've got so many fricking stupid problems.
        I remember one issue involving the air compressor where if it failed it would simply crack the whole god damned block or something.
