More details on the USS Fitzgerald investigation have come out

 

Quote

Their report documents the routine, almost casual, violations of standing orders on a Fitz bridge that often lacked skippers and executive officers, even during potentially dangerous voyages at night through busy waterways.

The probe exposes how personal distrust led the officer of the deck, Lt. j.g. Sarah Coppock, to avoid communicating with the destroyer’s electronic nerve center — the combat information center, or CIC — while the Fitzgerald tried to cross a shipping superhighway.

When Fort walked into the trash-strewn CIC in the wake of the disaster, he was hit with the acrid smell of urine. He saw kettlebells on the floor and bottles filled with pee. Some radar controls didn’t work and he soon discovered crew members who didn’t know how to use them anyway.

Fort found a Voyage Management System that generated more “trouble calls” than any other key piece of electronic navigational equipment. Designed to help watchstanders navigate without paper charts, the VMS station in the skipper’s quarters was broken so sailors cannibalized it for parts to help keep the rickety system working.

Since 2015, the Fitz had lacked a quartermaster chief petty officer, a crucial leader who helps safely navigate a warship and trains its sailors — a shortcoming known to both the destroyer’s squadron and Navy officials in the United States, Fort wrote.

Fort determined that Fitz’s crew was plagued by low morale; overseen by a dysfunctional chiefs mess; and dogged by a bruising tempo of operations in the Japan-based 7th Fleet that left exhausted sailors with little time to train or complete critical certifications.

To Fort, they also appeared to be led by officers who appeared indifferent to potentially life-saving lessons that should’ve been learned from other near-misses at sea, including a similar incident near Sasebo, Japan, that occurred only five weeks before the ACX Crystal collision, Fort wrote.

I've been swayed into thinking the Freedom based FFGX will be the likely winner, due to Saudi's basically paying the up front costs.

That is not their FFG(X) proposal. It's a proposed VLS module and SEWIP Block II refit to the existing LCS-1 class ship. This is their FFG(X) proposal (from SNA 2018)

Thank you for the correction, I haven't had a chance to go over SNA 2019 stuff yet.

Ten other sailors from the carrier’s reactor department were administratively disciplined late last year for their alleged ties to the drug ring, 7th Fleet officials said at the time.

US Navy to remove hard-kill torpedo defence from carriers

The US Navy (USN) will remove the prototype ‘hard-kill’ torpedo defence system from nuclear-powered aircraft carriers (CVNs), the Pentagon’s Director, Operational Test and Evaluation (DOT&E) has revealed.

   As reported by the RIA Novosti news agency on February 2, 2019, the Russian Electronics holding, which is part of the Rostec state corporation, has begun supplying the Russian Navy with 5P42 Filin visual-optical interference stations that blind the enemy. This RIA Novosti reported in the press service of the company.

   At the moment, the frigate "Admiral the fleet Kasaton", which is undergoing factory tests, and the frigate "Admiral of the fleet of the Soviet Union Gorshkov", which joined the fleet last year, are equipped with two sets of stations. Such equipment will also be installed on two frigates of Project 22350, which are being built at the Severnaya Verf.

   The station "Filin", developed by JSC "Experimental Plant "Integral", is designed to suppress at night and twilight time the visual-optical and optical-electronic channels of observation and aiming of small arms, as well as close range weapons, used against naval surface ships and boats. The action of the station is based on the modulation of the brightness of the light radiation. Low-frequency oscillations of the brightness of the radiation due to the excitation of the optic nerves cause temporary reversible disorders of the organs of vision.

   According to representatives of the holding, volunteers who experienced the impact of "Filin", noted the impossibility of conducting aimed fire from small arms on concealed targets when placed at a distance of two kilometers from the shooters' positions due to the lack of visibility of the target. At the same time, every fifth volunteer felt the hallucinogenic effect, and about half of the testers noted signs of disorientation in space, as well as nausea and dizziness.

   In addition, Ruselectronics added that outgoing radiation in the visible and part of the infrared spectrum, coupled with high-frequency brightness modulation, can effectively suppress infrared laser rangefinders, night vision devices, and anti-tank guided missile guidance systems at distances of up to five kilometers.

A blurb on the variation between Arleigh Burkes I copied in late 2014/early 2015 and forgot about.

Flight I/Flight II hulls as completed are 505 ft (154m) long and displace 8300-8400 tonnes. Compared to the others, they lack the hangar facilities, use older versions of Aegis and the SPY-1D, and have fewer provisions for minehunting and Littoral operations. But they also have the TACTAS towed array and the Mk-141 for Harpoon.

Flight IIA hulls as completed are 509 ft (155m) long and displace 9200+ tonnes. They make a number of major changes, most obviously the addition of the two hangars side-by-side on the stern to support a pair of helicopters and the elevation of the aft SPY-1D arrays 7 feet higher for clearance. The deckhouse was lightened and the hull thickened to bring the center of gravity down. Aegis and other systems are upgraded, and the crew accommodations are changed to support a slightly larger crew (for the helicopters) and to provide better conditions for mixed-gender crews.

Flight III hulls as completed will have mostly the same external dimensions as IIA, but displacement will increase to 9800+ tonnes. The primary changes revolve around the AMDR radar suite. The AMDR-S (SPY-6) replaces SPY-1D, power and cooling infrastructure is seriously upgraded, AMDR-X will be added starting with the 14th hull, and a number of officers quarters were moved up to the 01 deck just forward of the starboard hangar. A number of structural changes to the hull and deckhouse are being made to compensate for the increased weight of AMDR and associated equipment to preserve stability and a sliver of growth margin.

USS Arleigh Burke is actually a bit distinct from the other Flight I hulls and as a result DDG-52 through DDG-71 are sometimes called "Flight IA" to reflect the changes from Burke herself. Nothing massive, mainly lessons learned from the construction of the first-in-class were baked into the follow-on hulls.

Flight II lack most of the IIA's dramatic changes, and probably would be better served by a "Flight IB" label. Their most prominent addition was support for the SM-2 ER Block IV missile.

Baseline Flight IIA includes a grand total of two hulls, DDG-79 and DDG-80. Starting with DDG-81 there was a revision to the Mk-45 5" (127-mm) gun, the Mod 4 has a longer barrel.

After a few Flight IIA hulls were completed without either Phalanx CIWS mount, in favor of ESSM, the Navy changed plans and re-fit those ships with the guns. From DDG-85 onward they have been completed with at least one (the midships mount aft of the funnels) and the forward mounts are returning via refit as the funds have been available.

DDG-89 onward have a slight redesign to bury the funnels within the superstructure as a signature reduction measure.

DDG-91 through DDG-96 have a small enclosed area, sort of a third hangar, for the Remote Minehunting System.

DDG-113, 114, and 115 will be the initial re-start hulls as discussed above.

DDG-116 through DDG-123 will be "technology insertion" Flight IIA Restart hulls, with some of the non-AMDR related upgrades planned for the Flight III ships baked in.

DDG-124 though DDG-136 are intended to be the initial Flight III hulls. They will include most of the planned Flight III features except the X-band component of the Air and Missiles Defense Radar suite. Instead AMDR-S will be paired with the SPQ-9B X-band radar used by the Cruiser and Carrier modernization programs.

DDG-137 onward are intended to be the fully realized Flight III, or perhaps Flight IIIA, with AMDR-X replacing SPQ-9B.

Maple-syrup flavoured T26 is confirmed, after the legal challenge fell through:

Canada confirms Type 26 frigate selection

Canada has confirmed the selection of a Lockheed Martin Canada-led industry team to deliver the Royal Canadian Navy’s (RCN’s) next surface combatant using a design based on BAE Systems’ Type 26 Global Combat Ship (GCS).

 

I figure this makes it the largest single class of modern warships outside the US and chinese navies

A point of note: DDG-127 will be a Flight IIA TI ship, and will commission before the Flight IIIs. This is due to some rather complicated scheduling reasons (TL;DR: once the USN has assigned a hull number, they can't simply change them around).

 

Also, unless there is an (entirely possible) major issue with Large Surface Combatant, ships after DDG-138 are unlikely to be authorized. And it doesn't look like AMDR-X is going to happen anymore. DDGs will likely at some point start receiving the Next Generation Surface Search Radar that will go on FFG(X).

   State tests of the shipborne air defense system "Polyment-Redut" completed

   The state tests of the Poliment-Redut anti-aircraft missile system for frigates of project 22350 were completed. Commander-in-Chief of the Russian Navy Admiral Vladimir Korolev announced this during a speech at the assembly of the St. Petersburg Maritime Assembly, the newspaper Krasnaya Zvezda writes.
