Yes, the more complex transistor/IC designed electronics did require more power and more stable power. By stable, I mean that the power supplies had to convert AC to DC and more the DC more level at all times. Tubes never cared. IC and transistors were sensitive to varying DC levels and spikes. The electronics on ships became far more numerous and complex. Multiple radars like Search, height finders and fire control sets, sometimes more than one. Combat Information Centers with PPI scan scopes, multiples. UHF and HF radios, multiples. The list goes on and on. Those systems need a lot of stable AC power and backups. Also in 1957 we have the use of surface to air missiles like the Talos so now the electronics go even more complex as did the power requirements. Keep in mind, that all the equipment that I have described including the environments, need air conditioning to keep them cool and the humans servicing them. That will add to the power requirements and space requirements. Thank you for the reply Oldpop2000.
I always thought of the AC as being primarily for regulating humidity with temperature being a critical but secondary concern; like the refrigerated magazines. What springs to mind is the early AIM-7 Sparrows and associated radar having a bunch of issues in Vietnam due to issues arising from the tropical environment (and associated fungi / bugs / etc.). Seemed like they were often left too long on the planes before detailed check-outs / maintenance were done on them; but that is more of a training issue...
The problem, amongst many for the missile, was the fact that it was tested in the desert and then sent to Vietnam where the rain and moisture caused high failure rates. They had forgotten to coat the electronics with anti-moisture coatings. Once that was accomplished and the missiles were sealed so moisture could not get in, that one problem was solved. Another issue was the short lanyard on the LAU-7A which caused the plug to fail to pull off of the missile to allow the motor's to ignite. This was later corrected. |

Agreed, especially once SSMs come into play.
No offense intended here; but the name question doesn't interest me as it seems every country has its own name for the same entity and KE / Corvette seems to be a pretty good response to what could be a coding nightmare. What interests me with the question is if their will be a small ship (Corvette / Cutter / Frigate / what ever you want to call it) bristling with missiles and helicopters in the DLC... I would love the ability to add missiles / helicopters to small surface ships for TP and FS duty without them being an AMC or AV.
The small differences between a DD and Frigate in the 1960's-2000ish is that the Frigate were "generally" more focused on individual ASW hunting with shorter duration patrols and or coastal work (USA Coast Guard has Cutters which function very similarly to Frigates without the missile launchers, USCG Cutters have / had the ability to add missiles www.thedrive.com/the-war-zone/30604/coast-guard-cutters-once-carried-harpoon-anti-ship-missiles-and-they-could-again) with the DDs being more focused on integrated defense / feet support and deep water duties. Frigates also tended to have a little different berthing and electronic suites as well given their more independent roles. Different countries though did place different emphasis's on them and the above is a general Cold War view of the USA, China, USSR, GB, France, Japan - currently 55 nations have Frigates while a much smaller number of nations have a DD (I think it was 15-20 nations).
US Coat Guard Cutters did a bit of shore bombardment and interdicted coastal shipping during Vietnam - its pretty interesting.
I think destroyerhistory.org/coldwar/ is pretty enlightening . Specifically - "The US Navy’s purpose-built ASW escorts, initially referred to as “ocean escorts” (DE) but, from 1975, redesignated as “frigates” (FF), evolved from the destroyer escorts of World War II when it became apparent that leftover Fletchers, Allen M. Sumners and Gearings could not accommodate the electronics necessary for anti-submarine warfare." I've seen and read that article. You can read as many articles as you can, you will probably get mostly the same answers. The class of WWII destroyers were good, but the electronics for ASW at that time was based on tube technology. I've worked on tubes like the 5814 and others. The power supplies are very big and take up a lot of room, even on aircraft. The scopes etc. had the same problems. When we began to move to transistors and small scale integrated circuits, things got better. But by that time, those ships were no longer needed. The difference between an ARC-27 UHF radio used in aircraft was striking when it was replaced by the ARC-158 which was mounted in the cockpit. A major size change and heating change. There still are some of the old Gearing class Destroyers, still in service in other navies, like Dads old destroyer last I looked her twain was still getting good use out of her, and looking at photos of her, it is clear the swamped out her Torpedo launchers, for some kind of missile system.

Maybe with the new update, but what is the deference between a modern destroyer, and a modern Frigate. They both have similar mission profiles, Tonnage, speed and weapons fit. in many cases The only way I can tell which is which is to look at there hull code? What I want to know is if in the new expansion if we will be able to replace torpedo tubs with missile launchers, Like you see on world war II vintage Destroyers still in service, Like you can Replace gun Turrets with SAM's.
In reality different navies have different classification standards. The Royal Navy for example describes Frigate as an ASW escort and a Destroyer as an AAW escort - unrelated to their tonnage. A carrier strike group will require a mix of both.
Pakistan's Tariq class destroyers used to be Royal Navy frigates, while the Chinese Type 055 destroyer is described as a cruiser by the US Navy. Germany's Sachsen class frigates are twice the size of Brazils Almirante Brown-class destroyers.
By all means have a frigate category in game, but let us tag ships by role.
