i think I found my answer (or found 'an' answer) for the Mk38 Mod-4 30mm I note this navsea article. It specifically states: I have a fuzzy recollection of reading elsewhere the Mk 160 could handle different systems on the same warship , ... but i can't find that reference at present...

Indeed. I was pondering the same thing about parallax. For the Mk38 Mod-4 30mm (1 port, 1 starboard), each of which is, I recall reading, a Bushmaster-II 30mm gun on an RWS (remote workstation mount) , it has me thinking, from where does the original bearing and range originate? I believe...

One thing I am puzzling over with the River Class destroyer is how the fire control works to calculate the ballistics for the two guns (BAE Mk45 5-inch gun and also for the Mk38-Mod-4 30mm gun). Tracking: My assumption is for surface targets, bearing and range of the target (at the needed...

Reference the towed array sonar, my understanding is that, at present, the RCN is procuring the Thales Sonar 2087/S2087—a CAPTAS-family low-frequency active/passive towed-array sonar—for the River Class. Other warships in the world that operate or may procure this sonar or closely related...

I ma also curious about the proposed sensors for the River Class Destroyer, and what other countries my procure the same sensors. I note the Ultra Sonar Type 2150 (S2150) is planned for the River class — this being a digital, medium-frequency active and passive bow mounted or hull-mounted...

Also of curiousity to me, is the Navies that currently operate the BAE 5-inch gun, or are planned to operate such. I attempted to make a list of the warship classes currently with this gun, or those planning to install the gun on a new warship. My list (and it could have errors and omissions)...

This had me curious ... what other nations might be procuring the Mk-38 Mod-4 30mm gun (or an earlier variant, such as the 25mm). My rather tentative list ( where I could have errors or omissions): USN Arleigh Burke Flight IIA and III FF(X) frigate (exact variant TBD) potential (speculation)...

I don't believe I posted yet a link to this youtube video on the 30mm Mk38 Mod-4 gun: I still have not read anything official to confirm this is the gun, although everything (many different news sources/defenseforums) seems to point to that as being fact.

One interesting aspect re the German F128 (based on a Meko 200 design) for the 30-mm Seahawk (which may be the same as the RCN Mk-38 Mod-4 30mm gun), is that the Meko 200 design in some configurations will carry 3 x Vulcan Phalax (or 3 x Sea Zenith CIWS) per ship. In the case of the German F128...

As can be seen from above posts, I have been digging around on the web to see which weapons have seen combat. The plan is for the RCN River-class destroyers to install a 24-cell Mk 41 VLS. From what I can tell, the USN has used several Mk 41-launched weapons in combat, including SM-2, SM-3...

I think that is a good idea. I looked to see if there were any examples of any earlier predecessor of the Mk38 Mod 4 30mm gun used in combat (1) I do believe Mk-38 Mod2 25mm was used to fire warning shots at Iranian Islamic Revolutionary Guards Navy fast attack craft (2) I do believe Mk-38 Mod2...

As noted the RCN has dropped MBDA’s Sea Ceptor in favor of the Raytheon RIM-116 Rolling Airframe Missile (RAM) - as part of the River Class destroyer combat system. My understanding of this weapon system's purpose and its combat record is as follows: I read that the RIM-116 RAM is a supersonic...

Further to this ... I note a Naval news article ( Canada pivots River-class Destroyer combat system to Aegis and MOTS solutions to reduce program risk ) that claims the RCN is to include the AN/SPS-73(V)18 in the River Class destroyer. This has also been speculated on various internet sites and...

I have been watching (on again, off again) the AIS for the HMCS Robert Hampton Gray as she cross the Arctic, destined for Esquimalt. She departed the East Coast back in August this year, reference: Canadian warship begins historic Northwest Passage voyage from Halifax to Esquimalt I note a...

Possibly this 'trip down memory lane' on the shipbuilding of the DDH-280s has been posted before? ... I don't know. I just stumbled across it today and found it most interesting. A lot of what was being done at the time (gas turbine engines, two helicopter hanger with RAST (bear trap)) were...
