frigate

Hello all, just wanted to post some of the information I've gathered about various VT Halter designs over the ages for the United States and export, scanning through patent records and such. If anyone has anything else id love to see it. I have attached some of the key findings I have...

I saw on Wikipedia that the ships were fitted with Type 162 and Type 170B sonars when in service. Does that mean the class did not have a variable-depth sonar (VDS) at that time? After the modernization, did the Royal Netherlands Navy update the sonar systems? By the way, I noticed that the...

I assume I'm not the only one that has noticed the growing trend of utilizing inverted bows on large surface combatants that's emerging currently. As far as I am aware the Zumwalt-Class kickstarted the trend in the 21st century at least, with the French FDI following and Germany and Korea...

There are two photos in the ship design section of the introduction of Brown's "Rebuilding the Royal Navy": Is it possible to identify which projects they relate to? The plan on the screen is described as a frigate, and it appears as something between a frigate armed Type 42 and Type 22...

What are the specific differences between the Y-100, Y-136, and Y-160 machinery in the three batches of the Leander-class frigates?

Since there aren't any large threads for FREMM already, I figured I would create one specifically to discuss the background and development of the FREMM-EVO, a pair of interim frigates ordered for the Marina Militare Italiana. Background: Before we talk about the FREMM-EVO, we should talk...

The Norwegian Navy seems to be circling in on a few options for their new multirole frigates to replace the Nansen class. View: https://twitter.com/JUitdeketting/status/1814370088583086517?t=vNTJSQAK8fIzGqBC2yZnkw&s=19

I noticed that Heemskerck-class frigates have two 2D radars: LW-08 and DA-05/08. So this type of frigates don't need a dedicated height-finding radar or a 3D radar? How do they get the altitude of engaging targets?

Perhaps the most ambitious NATO programme of the 1980s was an attempt to design a common escort ship platform for NATO navies: NATO Frigate 90. https://www.secretprojects.co.uk/threads/nfr-90-and-other-pre-horizon-aaw-projects.923/ The project foundered as it became too expensive and failed to...

My working hypothesis is that the first two letters define the numbering series, and subsequent ones modify the first two. This is broken by DDGs and FFGs not falling into the DD and FF sequences, but otherwise it holds up reasonably well. Within submarines, there were the short-lived SC, SF...

A few months ago, I posted a thread on a briefing with several more or less obscure frigate concepts for the USN. One of the designs included in that brief is the PXM, which I described at the time as a rabbit hole. This thread is my attempt to chase that rabbit as far as I can go, starting from...

A few years ago when researching the photo archive of Kon. Mij. De Schelde succeeded by Damen Schelde Naval Shipbuilding I traced the next dia's, probably part of a lecture although without technical details

does someone have another photo of this ship model The one that appeared in indo defense 2022 expo yesterday and other information about equipment he used?

Starting a new thread on the Royal Navy’s Type 32. First some messages from the Type 31 GPFF thread:

The Royal Navy began the 1960s with two excellent classes of destroyer (County DLG).and frigate (Type 12 Leander) on order. In 1966 the replacement of these ships with the T42 and T22 was set in hand.. In addition the T21 gp frigate was ordered to replace other frigate classes. So not a lot of...

Wiki has quite a good summary of the abortive attempt in the 1980s to design a common escort ship for NATO navies https://en.m.wikipedia.org/wiki/NFR-90 The thread about the Kidds for the RN reminded me of this programme. It ought to have been possible to design a ship flexible enough to...

The RNZN has stated they will replace their two Anzac Frigates by the mid 2030s. See page 34 of attached. What do you think are the three most likely designs to be procured and how many? I believe by the 2030s, the deteriorating security situation with China in the Indo-Pacific will incentivize...
