Below I have posted two videos by Naval News, along with the breakdown of topics that accompanied the videos on YouTube. The video of the 30mm Mk38 Mod4 with its included electro-optic fire control system is probably of most immediate interest to the Coast Guard, but the increasing tendency to containerize weapon systems is appears ready to make any cutter (and almost any other ship) a missile carrier.

There was also a day three video.
00:47 – HII Remus 300 UUV
01:22 – HII electronic warfare system for unmanned vehicles
02:33 – HII mission technologies / Amazon’ snowball
04:30 – USS John F. Kennedy (CVN 79)
05:10 – Virginia-class Block V submarine
05:43 – Columbia-class SSBN
06:20 – U.S. Coast Guard National Security Cutter (NSC)
06:45 – DDG 51 Flight III Jack H. Lucas destroyer
07:10 – USS Bougainville (LHA 8) America-class
08:07 – USS Harrisburg (LPD 30) San Antonio-class Flight II
08:54 – Austal EPF Flight II
10:00 – General Dyncamics NASSCO new ESB versions
Not much of immediate interest to the Coast Guard. It shows a model of the NSC but that is all, nothing new there. The Coast Guard might have reasons to interact with the Austal EPF II with its increased medical facilities and better boat handling capability.
We might have interactions with the NASSCO ESB, particularly when SOUTHCOM gets their ship of this class. I can’t believe these ships don’t have the facility to refuel other ships. What is a “base” without fuel. To provide that on a ship based on a tanker seems like a no-brainer.
Another video. No Coast Guard content. this one about the MQ-25, carrier based UAS https://www.navalnews.com/event-news/sea-air-space-2022/2022/04/video-mq-25-stingray-uas-program-update-at-sea-air-space-2022/
Dated 31 August 2022, US Navy cancelled Raytheon’s AN/SQS-62 “DART” Variable Depth Sonar…
That happened when they killed the LCS ASW mission module back in March. https://www.defensenews.com/naval/2022/03/31/us-navy-to-terminate-dart-sonar-development-with-raytheon/
