One of three guided missile frigates purchased by Neodoros from South Cordar. In 1982, a shipyard in South Cordar was experiencing financial difficulties, and the owner's home country, Neodoros, decided to come to its aid, and was able to purchase three custom-built guided missile frigates at a favourable price. Since the situation in the vicinity is stable, there is little pressure on Neodoros for national defence. Therefore, the three frigates are equipped only with short-range ship-to-air missiles and light anti-ship missiles, as well as one 100mm gun and two twin 37mm rapid-fire guns. As there is no need for anti-submarine warfare, there is no helicopter hangar, only a helideck designed for service needs, and capable of taking off and landing anti-submarine helicopters if necessary.

Hi Rbz88, I like the extra top view. Any details on armament, helicopter type, propulsion etc? Also is it really an FFG as the missiles forward look like short range SAMs?

Reminds me somewhat of a Kortanaer or Karel Doorman FF, in terms of general arrangement, though without the ASW focus. (No helicopter hangar in the 1980s however seems like an unusual choice!) Wondering if you used any real designs for inspiration or which you would consider comparable?

Vosper Mk 8 Frigate, Maehe Class


Maehe, as commisioned in 1978

The withdrawal of the raft of small escort ships leftover from WW2, The Mynoghran Navy set about acquiring a modern replacement. Eyes drew to the Royal Navy's Type 21 Frigates which were all just completed or being built. The Type 21's origins stemmed from under British political and Treasury pressure for a relatively cheap, yet modern, general purpose escort vessel. On the surface, this seemed to have been achieved with the Type 21s (The weaknesses revealed during service were not yet known.) Given all this, The navy approached Vosper Thorneycroft, designer of the T21s to create a improved, slightly smaller design more tailoured to south pacific service. Given that the navy had recently ordered a quartet of modified T42 destroyers, long range air defence was not considered - more focus was put on close range air defence and ASW capability.

6 Ships were ordered, 3 being laid down in 1974 and 3 in 1976. They would proove to be good seaboats despite their small size. They were upgraded in the early 2000s, with the obsolete seacats and .79" cannons being replaced with Phalanx CIWS and the native Fasioti Short range SAM. As of the present 3 still serve, 3 being withdrawn in 2005, 2017 and 2019 respectively.

I like the drawing.

From a realism perspective, I wonder what tradeoffs would be necessary with the smaller hull size relative to the T21s (8-10m shorter, 0.8m less beam). Stability might be impacted… especially with the heavy twin 3” mount forward (though replacing the Exocets with SeaCat should save some weight… interesting choice by the way, rather against the times). Perhaps consider reducing the mast height or replacing with an Oto 76mm compact? (Or keep the same beam as the T21s)

Also might be worth simplifying the propulsion arrangement as this is an export frigate and a Pacific navy which would want good range… Yarrow was using CODOG for its small Malaysian & Indonesian corvettes at the time (1x Olympus + 1x diesel), and the Wielengen class (1x Olympus + 2x diesels) also comes to mind… should still be good for 27-30 knots with a single Olympus.

Thank you for the feedback, ill make the changes to beam and propulsion as you reccomended.

WestPacT-FR Program

WestPacT-FR (Western Pacific Treaty Frigate Replacement for 90s) was a multi-national programme designed to produce a common frigate for several Western Pacific nations, and intend to export to other countries, including some from Southeast Asia, Central and Latin America. Different design variants and concessions made in this program based on different requirements needed by every nation involved in this program.



Development

The project sought to achieve economies of scale in the production of the next generation warship. Feasibility studies began in 1985 and reported that with a modularity in design, low cost for availability for other countries and chosen weapon requirements, collaboration should be possible.

This program was led by Vestricia joined by Taiwan, Japan, South Korea, Australia, and New Zealand under West Pacific Treaty of 1981.

Like in the NFR-90 program, arguments erupted in the design definition stage over such issues as the choice of a primary anti-ship weapon. Taiwan pushed its domestic missile they had developed while the majority of the nations preferred the Boeing RGM-84 Harpoon. Australia, Japan, and South Korea, in particular, were uneasy about the lack of space needed for installing the Mark 41 Vertical Launching System. Japan is also interested in having a size of a destroyer rather than a frigate in order to protect their maritime territory against Chinese incursions in the Senkaku Islands.

However, unlike the NFR-90 program, the Vestrician government and Admiralty made a motion to build the final design they made during discussion between nations in order for other countries to modify on their own based on the various requirements needed by every nation.

The first WestPacT frigate under the Vestrician variant was laid down in the Winter of 1989 by Mitsubishi Heavy Industries in Oosora City.

Hello, H_K, thanks for your feed back ! In response to your query, I've just added two or three short notes. To be honest, there is no helicopter hangar as this AU country has relatively low defence pressure and little chance of encountering hostile submarines. As for real life references, for the stern section I was referring to the 053hth exported to Thailand.

Orla-class Light Patrol Frigate

In lieu of the two Peacock class vessels originally intended for purchase from Britain, the Irish government opted for a pair substantially more capable vessels from Vosper Thornycroft based upon their existing Mk.18 export frigate design. The resultant pair of vessels Orla and Ciara were duly ordered in 1985 and completed in early 1989, serving until 2008 when they were both retired, being sold on to Romania.

Zhenya Mikhailov class frigate


First, of her class, CCIN escort ship #128 was the first of this type of ship adopted by the CCIN naval security forces when global trade routes were threatened by a submarine raiding force blocking important food and material shipments to member nations designed in Arstotzka then built in 7 different member nations this class of ship would balloon to a whopping 55 ships built for just the global war of 1974 during which the ships would find themselves protecting humanitarian shipping and military convoys all across the globe. Post-war most not destroyed and found in good shape would continue to serve into 2002 with the major navies as training ships and border guards, some smaller navies continued to operate these until 2015 in differing states of disrepair and refit.

Hi everyone!

F-2800-Class Frigate

During the 1970s, the French developed a series of export frigates in three sizes: The C-1800 corvette (no sales), the F-2000 frigate (four sold to Saudi-Arabia) and the F-2800 frigate, the most successful type, of which four each were purchased by Chile and Pakistan.

Resembling a bigger (only marginally longer, but beamier and deeper) F-2000 with more freeboard, better seakeeping and improved structural resilience, the F-2800 was designed to operate in open waters under challenging weather conditions, where the F-2000 would likely quickly meet the limits of their seakeeping abilities. F-2800 also was better equipped for ASW than the primarily antiair/antisurface focused F-2000, mounting the same bow sonar as contemporary French Georges-Leygues-class frigates, had hangar space for two helicopters rather than only one, and were equipped with a sextuple Bofors 375mm ASW mortar forward, with a limited secondary short-range shore bombardment capability. Common features were the all-diesel propulsion and the austere radar equipment, which was limited to a single air/surface search set, a navigation set and a helicopter approach set, and the lack of VDS. For armament, different options were offered, including italian and US gear. By the time the design was finalized in the early 1980s, the market for such ships was more or less saturated with Italian and German designs, and attempts to sell the F-2800 to Portugal, Greece, Colombia, Peru, Iraq and Malaysia all failed. Morocco and Egypt also showed interest, but ultimately could not afford new-built frigates. The lead customer eventually became Chile's Pinochet regime, who - grasping the chance to overtake Argentina after the virtual annihilation of the Argentine navy during the Patagonian War - placed an order for four ships in 1983. The Chileans went for the Spanish Meroka CIWS for close protection and MM40 Exocet missiles for antisurface work; they also chose US 324mm torpedoes instead of the French standard 550mm ones. They were delivered between 1986 and 1988, and were dubbed the Uribe-Class. Pakistan, who had purchased two French submarines from a South African order in 1977 and was satisfied with their performance, was also willing to invest in new-built oceangoing frigates and re-activated the French Connection in 1985, ordering a class of four, which were delivered between 1989 and 1991 (named Khaibar, Saif, Aslat and Jinnah); they featured different armament, substituting Phalanx for Meroka and Harpoon for Exocet. Despite aggressive marketing, no further sales were secured, and the type was considered obsolete by 1990 due to its complete lack of stealth features. In service, these ships proved to be sturdy and easy to maintain, and ran up a long service life; the Chilean vessels were retired between 2015 and 2017, and of the Pakistani batch, the last one lasted till 2022. One Pakistani unit (Saif) was blown up and lost with all hands in 2002, probably by islamist members of her own crew; all others were scrapped.
