There is a fairly significant vessel missing from the US Navy inventory - the Mark V Special Operations boat. Here is Wikipedia information, which is hardly authoritative, but the boat has been in operational use since at least as early as 2003.

65+ knots, significant range and weapon capability. Carries 14 SEALs and the boat crew. As much as we all enjoy the Cold War / Hot War scenarios, it seems the future may dictate more littoral missions and conflicts.

Edited to fix link with a "real" computer.

They are there as well as the new Mark 6

Make sure you're using a current db and search for US Mk5 etc.

Could you try increasing their proficiency and let us know what the results are?

The photo in the 444 database for the Mk V (and the data) is for the Pegasus (PHM-1) that entered service in the 1970’s and decommissioned in 1993. I cannot find it anywhere listed as the “Mk V SOC”. The Pegasus was a 48kt capable hydrofoil. The current Mk V is not a hydrofoil and is listed simply as 65+ kts.

The Mk 6 is a riverine/littoral craft first delivered to the Navy in 2014 and is not directly connected to special operations. The Navy calls the Mk 6 a “patrol boat.”

Near as I can tell, the photos and data in 444 is correct as far as it goes, but certainly does not have the Mk V SOC. There is a pretty good set of photos and data (non-Wiki) at warboats.org. You have to put “MkVa” (no quotes) if you have trouble browsing like me. The boat itself carries 2 11m RHIBS and a variety of weapons.

Thanks

The 9X Block II can do things its predecessors could hardly have imagined. For example, it is equipped with a 360-degree engagement capability and a data link, said Capt. Jim Stoneman, chief of the Navy’s Air-to-Air Missiles Program Office. That enables a pilot to fire the missile first and then aim it at a target.

“The pilot can shoot and then pass more information to the missile” via the data link to vector the missile to a target, Stoneman said during a briefing May 16 at the 2016 Sea-Air-Space Exposition. The missile’s 360-degree capability enables it to engage targets — even those behind the aircraft, he said.

On some planes, such as the F-35 Lightning II Joint Strike Fighter, pilots will be able to aim the missiles using sights built into their helmets.

Although the Sidewinder was developed as a short-range missile meant for close-in kills, the Block II’s range has been “about doubled,” Stoneman said, making it into a “beyond-visual-range” weapon.

The Navy’s V-22 Osprey program is working toward fielding an aerial tanking capability for the Marine Corps’ MV-22B tiltrotor assault transports by 2018, the program manager said.

Col. Daniel Robinson, the Navy’s program manager for the V-22 Osprey, speaking to reporters May 16 at the Sea-Air-Space Exposition at National Harbor, Md., said the “summer of 2018 is the target for this capability.”

quote:


The Navy has tentatively moved up the down-select decision for the new frigate design to 2018 from 2019 and has given the lead ship a hull number.

Speaking to an audience May 18 at the Sea-Air-Space Exposition, Capt. Dan Brintzinghoffer, the Navy’s program manager for the frigate program, said the first new frigate would be designated FF 29, the next sequential hull number after the 28 littoral combat ships (LCSs).

...

The frigate will incorporate most of the features of the anti-surface and anti-submarine mission packages of the LCS, including the 57mm and 30mm guns, Hellfire Longbow missiles, Multifunction Towed Array, variable depth sonar, MH-60R helicopter and MQ-8C Fire Scout unmanned helicopter. It also will be armed with the SeaRAM missile launcher and an over-the-horizon (OTH) cruise missile.

The OTH missile will be selected through a full and open competition, he said, and is at the top of the list of features for the frigate.

The Navy is deploying the Harpoon cruise missile on the LCS USS Coronado and the Kongsberg Naval Strike Missile on the LCS USS Freedom, but these demonstrations are different from the missile competition for the frigate.

The combat system for the frigate was selected by the Navy when 2019 was the intended down-select year: the Lockheed Martin COMBATSS-21 system.

quote:


The first eight Freedom variant LCSs are being delivered with the Airbus Defence and Space TRS-3D/16 G-band radar, designated AN/SPS-75 in USN service. However, the remaining eight vessels - starting with USS Indianapolis (LCS 17) - are to be fitted with a rotating version of the TRS-4D system as an 'in-line' upgrade.

Based on solid-state Gallium Nitride technology, TRS-4D is a software-driven radar employing full digital beamforming, and with pulse-Doppler processing in all beams. The rotator variant features a single-face AESA antenna rotating at either 15 rpm or 30 rpm (depending on the update rate required) at 2-70° in elevation. The use of an AESA array, with instantaneous dual-axis beamsteering in both azimuth and elevation, allows for 'backward scanning' to ensure fast-track initiation.

The SeaRAM is already installed on many of the trimaran hull Independence variants of the LCS and is slated to be integrated onto the Freedom variants starting with LCS 17.

Initial Operational Capability projected for FY2018, subject to ship availability and operational requirements

quote:

Leveraging technology and experience accrued from Kongsberg's previous development of the Nytt Sjømålsmissile/Naval Strike Missile anti-ship missile, JSM has been conceived as a low-observable, air-launched precision strike weapon designed for integration and internal carriage on board the F-35A and F-35C variants of the Lockheed Martin Lightning II Joint Strike Fighter (JSF). Norway plans to purchase 52 F-35A aircraft to meet the Royal Norwegian Air Force's (RNoAF's) Project 7600 Future Fighter Capability programme requirement; authorisation has so far been received for the procurement of 22 F-35As.

Integration of JSM into JSF is planned as part of the Block 4A/4B update, due in service in the 2022-2024 timeframe; this would enable the RNoAF's F-35 fleet to achieve full operational capability in 2025.

AFSOC anticipates that the Silent Knight retrofit kits will be available in the third quarter of fiscal year 2021. The command is looking to fit one to two CV-22s with the new system in fiscal year 2021. From fiscal years 2022 through 2027, it plans to retrofit eight to nine aircraft per year. However, that schedule is dependent on aircraft availability and the length of the other retrofits. Overall, the command hopes to have the new radar on all 51 CV-22s by fiscal year 2027. Silent Knight has already been tested and integrated on Army special operations helicopters — the MH-47G Chinook and the MH-60M Black Hawk, Lemaster noted.

Problem was fixed by creating a new SOSUS unit and placing it in deep waters. By merely moving an existing one from shallow (where its arrays do not operate due to shallow depth) into deep waters, the operational status does not automatically change.

Thus, the newly created US and Japanese SOSUS units operated fine, while the displaced Chinese SOSUS did not.

Which is a lot smarter than your original post.

Nobody here is purposefully manipulating data toward a US bias and it really is annoying to be accused of it.

According to program officials, software development and
integration of the electronic warfare system with all other on-board and off-board systems are risk areas that
could affect the Air Force's ability to have the required number of assets ready in time for the projected initial
operational capability in 2021.

To further improve schedule, affordability and program risk outcomes, and consistent with the
JROC approved CDD, the F-15 EPAWSS program will pursue a two-increment acquisition approach. Increment 1 replaces the existing Radar Warning Receiver, Internal Countermeasures System and Countermeasures Dispenser System. Increment 2 adds a towed decoy / angle countermeasure capability.
