Hard to comprehend that I've been working on this now for three years. So many revisions to make, so many drawings to do so much in general to do. :shock:

------------------------------------

Off the West coast of Ireland lies the Isle of Atlantia, a crowned republic and former dominion of the United Kingdom. Atlantia is a large continental island with a heavily fractured coastline. Plate tectonics have had a great deal to do with shaping Atlantia and its geology, there are extensive mountain formations crossing SW-NE some of which containing active volcanoes culminating with the White Peak and Black Mountains which contain the two highest peaks in Atlantia.
The further North in Atlantia you go the more mountainous and rugged the terrain gets whereas the further South you go the terrain flattens out into vast swathes of agricultural land and woodland.
Across the North-South extent of the island (N62 12.391 - N52.295042) there are prevailing westerly winds throughout most of the year from the Atlantic ocean temperatures remain quite warm on the East and South coast year round resulting in some peculiar wildlife events of species normally found much further South.
The higher latitudes of the interior are classified as sub-Arctic (Dfc) being cooler on average than the surrounding lowlands. The West facing coast and associated interior areas up-to the mountains are classified as having an Oceanic climate whilst the opposing coast and most southerly expanses feature a humid continental (Dfb) climate.
Around 60% of the current economy relies on substantial pockets of coal, gas and oil. In particular there are at least three known vast seams of anthracite with an estimated 10 billion tonnes of extractable reserves. There are substantial oil/gas fields on the East coast which for many years have been severely contested about with Ireland. In 2010 a survey along the West coast discovered stretching for some 50 miles in length and 10 miles in width, it has been estimated that the field has a potential yield of some 9.1bn barrels.
Mineral wise there are substantial deposits of malachite and azurite to be found in the North-east of the country with a yearly output of some 700,000 tonnes. All in all, the mountainous regions of Atlantia play host to some of the richest mineral deposits in Europe not just limited to copper.

Atlantia receives power from three main methods, geothermal, hydro-electric and nuclear the former have recently started to replace coal burning plants to combat pollution, there have been studies to increase the cleanliness of coal plants in recent years to make use of the vast deposits of coal on tap though as yet these studies have come to nothing. The vast majority of power in Atlantia comes from nuclear plants the first of which was built in 1966.

Atlantia features an extensive motorway/highway network which circles the coast of the island and crosses it in 3 strategic routes as well as several smaller more minor routes. An extensive rail network also covers the island with around 80% of the island's inhabited areas have a rail connection of some kind. There are high speed lines running in parallel with the main highways refereed to as HS1, 2 and 3

There are many rivers in Atlantia with the two of greatest importance being the River Holloway and River Trent. The mouth of the River Holloway is not far from the capital city of Atlantis and as such has 2 major ports on it and the River Trent is worth mentioning due to the fact that it runs nearly the entire length of Atlantia.

Today Atlantia is a thriving technologically advanced nation with a population of over 139 million. Whilst industrial expansion and large increases in agriculture and the population have made dents into the natural reserves of Atlantia the country is not as worse off as others. During the late 60s and early 1970s the government passed a bill limiting what could be taken from the land to preserve the reserves and natural beauty of the Island. In recent years there have been amendments to this act to allow greater exploitation of resources however this has to be where sustainable and non-invasive into the landscape.

The fauna of Atlantia is quite diverse. The southern parts of the country are of mainly temperate deciduous woodland where as the further North you travel the more abundant coniferous species become such as Norwegian and White Spruce, the most common species of deciduous tree found in Atlantia is the Red Oak of which there used to be immense forests of spreading almost to the Black Mountains.

Family Snapshot...

Basic drawing of the class as they were in and around 1985
[ img ]

HMAtS Aufaniae depicted in the state she was in during the Falklands Conflict of 1982. For this deployment (along with HMAtS Andraste) she was hastily painted into a dazzle scheme in an attempt to confuse any Argentine pilots making a run at her. She also landed a good part of her air-group (mainly from the lower hangar) in order to get troops and their transport/equipment to the Falklands in as short a time as possible. (Andraste on the other hand maintained her full air group with the addition of some extra helicopters which were part dismantled and assembled on arrival in the Falklands) As you can probably see on the deck of Aufaniae there are a few types of helicopter. The largest of these are Bell 214STs which were quite new to Atlantia at the time of the conflict, the more recognizable (I hope) helicopters take the form of AB.205 (Huey) utility transports and AB.209J Sea Cobra gunships. Also if you look close enough you can probably see the air-assault soldiers in their transports...
[ img ]

HMAtS Andraste depicted as she was in 1985. Experience during the Falklands had shown that whilst the 76mm was a capable anti-aircraft weapon it's rate of fire was too slow to keep up with the speed that Argentinian aircraft were ingressing and egressing from the vicinity. It was noted however that the four twin 40mm mounts had proved much more successful in both damaging and deterring attacking aircraft by the sheer amount of flak they could throw into the vicinity of the attackers. Andraste was originally slated to receive an all 35mm armament replacing both the 40mm and 76mm weapons but this idea was shelved when 40mm twin mounts became available from ships being decommissioned.
[ img ]

Finally a much more fluid drawing in terms of updates and the like. This depicts the rolling concept and ideas of what these vessels will receive in terms of an MLU and SLEP around about now. As you can see the 76mm compacts have been replaced by four Strales mounts more suited to the job of AA than their predecessors (one hopes). The 40mm twins have been replaced by 35mm Gatling CIWS mounts in slightly enlarged sponsons (to accommodate the magazine and computer systems for them). The blank area below the FA-15 about to take off I'm not sure what to do with. I could fair it off in line with other parts of the overall sponson or I could mount a CISAM (RAM) launcher in there (both P&S). There is an AVLS2 replacing the Mk26 containing most of the SAMs and indeed decoys (the two munitions to the right of the set). Sensor wise I don't really know what to replace LW-08 with (if anything). Other sensor changes include the deletion of STIR and it's replacement by two new units for datalinking and missile illumination (for alternate firing modes on the Armaros missiles should they be required). There are SCOT directors (Ku and EO) for the 76mm mounts (when not using DART which is guided from the mount). The modules you see below them are LADAR CIWS targeting units linked with the 35mm CIWS providing alternate targeting from the on-board EO gimbals. The SLQ-32 has been replaced by it's Atlantian equivalent too. There are new and replacement countermeasure dispensers dotted around including; en-mass chaff and flare launchers, acoustic decoys and HarK launchers. From the perspective of the air group the Buccaneers would have been phased out and replaced by for the most part more FA-15Ns though due to cost this was cut short from the total number of airframes needed. (F/A-18As + Bs or Cs and Ds leased from the US would fill the gap whilst a new aircraft was debated in parliament). The F/A-18E/Fs you see are purely speculative but I imagine for lack of a better aircraft they are what will be selected eventually... The turbo trackers, traders and tracers are starting to show their age by now even though they are good for another 5-10 years their replacements are already starting to appear in the form of the MFD Prion. They replace their predecessors in all three roles with the exception of ASW with which the Prion has predominantly done away with in favour of generic MP (ASW is still carried out by helicopters). The AB.212s and 412s operated have been in recent years complemented and in some cases supplanted by WS70 Seahawks for both the ASW/MP and utility roles, whilst the former types will still serve it is thought that they may be relegated to crew training and domestic missions leaving the WS70 as the sole helicopter used by NAVCOM for shipboard deployment. I expect these 5 vessels to soldier on to between 2025 and 2030 depending on how quickly their successors are developed and built.

Well after an even more protracted development (drawing) time I've got around to doing even more tweaks to the millionth iteration of the Gemstone, this time with some helpful input from other members put into them

Abstract:

Stemming from the CNGF project the Gemstone class of destroyers as one can probably tell ended up being full on destroyers in both displacement and capability terms leading to another design to replace ageing frigates. Like the UK Atlantia decided to leave the partnership that would end up with the Horizon class to develop what they had already developed. The result was a family of destroyers outwardly similar in appearance to the Horizon class albeit being slightly larger in all respects.
Unlike the Horizon class the Gemstones were designed to make use of the COGLAG style of propulsion rather than CODOG. During development there was talk of moving towards the as yet unproven SYLVER launching system over the the proven American made Mk.41. Politics however intervened and rather than SYLVER it was decided that Mk.41 would be installed to promote US relations (that said IRL SYLVER is to undergo integration of Mk41 capable munitions).

Future:

There are currently 34 Gemstones in service with the Atlantian Navy, their future is pretty much guaranteed for several decades current pipeline upgrades include operational integration of UAV/UCAVs, integration of NSM to supplement ASALM, supplanting SM-2ER with SM-6, operational clearance of CAMM and possible integration of other SYLVER capable munitions.

Combined Task Force 150 Stuff

[ img ]
[ img ]

Whilst on operations in the Indian Ocean HMAtS Diamond, Adamite and Emerald have all carried 'dazzle' schemes reminiscent of the Falkland schemes of some years back. The first scheme to be deployed was actually scheme 'B' which turned out to not be as effective as hoped, scheme 'A' was substituted on vessels deploying as a part of CTF-150. To suit the warmer waters that they semi-permanently operate in they have also received different anti-fouling arrangements.
For their deployments they land their ASW helicopters in favour of a SOFCOM MH.II Blacktip (MH-60M). Their forward and aft 'flex' areas have been organised to facilitate detainment of pirates and other undesirables as well as the embarkation of a larger than usual complement of boarding personnel made up from Atlantian SOFCOM personnel and SECFOR personnel.
On two occasions there have been TLAMs fired against targets in Somalia resulting in the destruction of both men and material.
Starting from 2014 the centurion countermeasure dispensers amidships will be retrofitted to fire Spike-ER surface to surface missiles to deal with skiffs and other vessels encountered also from operational experience the Batch 5 vessels now deploying to theatre will do so with an MH.I "Black Magic" SOFCOM transport helicopter (AW101) and Merlin HM.IA weapon capable transport.

Abstract:

The Metallurgical class are the most recent design of frigate to enter Atlantian service. With a design period of over 7 years they they have been through the mangle when it comes to changes to the design. The original specification called for a 110m vessel capable of deploying a towed array as well as on-board sonar and permanent accommodation for a helicopter. Post Falklands this requirement swelled to include local air-defence and anti-surface rolls resulting in a lengthened and broadened design with small and medium calibre artillery as well as the hastened introduction of NSSM-VL.
By the time the first vessel entered commission in October 1991 the Cold War was no longer the threat that it had once been and the implosion of the Soviet Union once again meant looking at either Palladium being a unique vessel or further diversifying into a true general purpose warship which was what frigates were now deemed to be.
Between 1990 and 2000 a raft of improvements were carried out to bring the class and new builds to MLU-1 standard. This involved the substitution of the twin 30mm amidships with a CIWS proper in the form of the Oerlikon Contraves 25mm Phalanx. Link-11 and then Link-16 datalinks and the integration of new weaponry in the form of ASALM and SM-2MR. MLU+1 saw the introduction of SMART-S Mk2 3D radar, ESSM and Stingray MOD 1 torpedoes whilst MLU+2 sees the introduction of Nulka and Centurion countermeasure dispensers and an improved SLQ-32. The class has proven to be a useful one thus far and it is intended that they will remain in service or at least some of them until 2040.

Future:

As yet unspecified improvements and refinements are likely to take place before 2015.

Design:
The basic design of the Patriot class is quite a beamy hull with pronounced flare and knuckling towards the stem with a soft chine leading from it to the stern in an effort to maximise volume and reduce wetness much like the preceding Patriot class of destroyers...
The vessels are powered in a COGLOG arrangement with since their MLU 2x GE LM500 turbines providing cruise power, 1x GE LM2500 turbine providing boost/sprint power and a LM500 based ship service generators (During their MLU they received LM2500+ turbines which replace their earlier Speys as well as improvements to their gearing set-up.
Other modifications that have been undertaken in recent years is the application of new antifouling paint and a transom flap. These enhancements have provided the class with an increase in attainable speed to 32 knots (Kovar attained 35.21 knots during high speed trials in 2006) and reduced fuel usage somewhere in the order of 11%.

Abstract:

The Patriot class are one of two to precede the Gemstone serving from 1984 and expected to be fully retired by 2014 they have had eventful lives being deployed to the Arabian Gulf for both the first and second invasions of Iraq. The Sanchez was damaged by a small boat filled with explosives whilst in harbour in Aden killing 33 of her crew and injuring a further 19. Both Oswald and Tasha Lem saw action in the campaign against the Muammar Gaddafi regime with the former engaging a Libyan frigate attempting to leave harbour with both 127mm gunfire and an RGM-84. Oswald consistently sailed close to the Libyan coast providing NGFS under direction from 30AU and 32AU personnel. During these actions Oswald was credited with the downing of a Libyan Mi-24 with one of its RAM launchers.

Future:

They are due for complete retirement by 2014 when Gemstones will have fully taken over their roles in one form or another. As of 6/6/2013 the vessels remaining in service were as follows:
  • H-200 - HMAtS A. G. L. Stewart
  • H-203 - HMAtS Lorna Bucket
  • H-204 - HMAtS Tasha Lem
  • H-207 - HMAtS Augustus Oduya
  • H-209 - HMAtS Oswald
  • H-211 - HMAtS Muriel Frost
All of the Harkness sub-class were retired by 2010 and laid up awaiting disposal as of 6/6/2013. H-219 is however expected to return to limited service as a trials ship.

Design:
The basic design of the Patriot class is that of a long slender hull with pronounced flare and knuckling towards the stem with a soft chine leading from it to the stern in an effort to maximise volume and reduce wetness (hence the bulwarks too).
The vessels are powered in a COGOG arrangement with 2x GE LM500 turbines providing cruise power, 2x GE LM2500 turbines providing boost/sprint power and 2x AG9140 ship service generators (During their SLEPs they received LM2500+ turbines replacing their earlier LM2500s as well as improvements to their gearing set-up.
The class originally featured open quarterdecks which in recent years have been plated over due to their almost constant wetness, the resulting expanse of space has been gladly utilised by the crews of remaining vessels.
Originally fitted with 4.5" Mk.8 mounts the class were retrofitted in their SLEP with 127mm mounts due to the 4.5/114mm calibre being abandoned in favour of the more common 127mm.
Other modifications I feel are self explanatory...

Cheers!

The first of the two drawings has now been completed and as such follows with details.

  • Unbroken or 'U' Class Submarine (SSI)
  • Produced:2001-2010
  • In Commission: 2003 Onwards
  • Displacement: Surfaced:~1,600 Tonnes Submerged: ~1,730-1,800 Tonnes
  • Length: 75.5m
  • Beam: 7.5m
  • Draught: 5.7m nominal
  • Test Depth: >300m
  • Propulsion:
    • 2x MTU 12V4000 U83 diesel generators @ 1,300kW ea.
    • 10x Siemens 35kW fuel cells (4x 90kW cells from S-527 onwards)
    • 1x Siemens 2000kW motor
    • 4x 150 cell batteries
    • 1x retractable auxiliary propulsor (in this case a VSP) for fine and slow, silent manoeuvring
    • Main propulsor is a 13 blade shrouded affair.
  • Speed: Surfaced:12 knots Submerged: 20 knots
  • Complement and Accommodation: 5 officers and 20 ratings plus austere accommodation for a party of 12 special forces personnel
  • Endurance: 60 days before resupply
  • Range: 10,000km @ 10 knots (surfaced) - 30 days without snorkelling
  • Armament: 4x 533mm torpedo tubes, 2x 400mm torpedo tubes and a multi-purpose dock/lock between the torpedo tubes (for divers / SF, UUVs, mines or non-reloadable weapons)
  • Up-to 12 reloads can be carried for the 533mm tubes as well as a further 4 to 6 for the 400mm tubes (which can double stack torpedoes)
    Weapon Systems Employed:
    • WASS Black Shark heavyweight 533mm torpedo
    • Saab Bofors Dynamics Type 43X2 / Type 45/46 lightweight dual purpose 400mm torpedo
    • BAE / MBDA Sea Eagle (Sub launched spin-off)
    • Deihl BGT IDAS SuAAM (under evaluation)
    • Dillon Aero M134 (mast mounted)
  • Sensors: (Fitted from new or refitted from 2006 onwards) Thales UWS S-Cube integrated sonar suite as well as Thales UWS supplied air and surface search radar sets and control consoles / C4ISR equipment
ETA: Missed some stuff off of the specifications as well as W class follow on.

Warrior or 'W' Class Submarine (SSI)
[ img ]

Similar in design to the U class with a revised single pressure hull instead of the compounded one on the 'U' class. These vessels loose the multi-purpose dock in the bow and gain another pair of 533mm torpedo tubes. They also feature silos aft of the sail for either TLAMs or other vertically launched weapons. Weapon storage goes up with the loss of the SF accommodation to 16 533mm weapons and 8 400mm weapons.
Range is somewhat similar to their predecessors being capable of attaining some 10,000km at 10 knots. Their endurance however has increased via the new found storage space to 90 days.
S-550 was laid down in 2009 and accepted into commission in 2011. S-551 followed in 2012 and S-552 in February 2013.

Interesting hull design, I am wondering what some of our expert members have to say about this one.
Sensor suite seems fine ;)

I may change it at some point depending on what people say. I presume you're talking about the destroyer?

As I've mentioned before, you're going to have some major load issues with a non center mounted engine.
You'll also want to move the thruster forwards so that one, it won't interfere with the VLS and two, so that you'll get the maximum effect out of it. (Mass x Lever is also true on ships.)

I realise the Dutch Youth Brigade is going to kill me for this, but is the I-mast capable of handling all those systems ant once and still provide enough detection range?
We're talking six different missile systems that all needs illumination/guidance, a gun that also needs direction plus air and surface search.
Also, placing a Goalkeeper on the hangar is a bad idea due to its deck penetration. As it is, I doubt you'll be able to fit in that helicopter and still have enough headroom to perform maintenance.
If having a goalkeeper is important to you, then swap it out with the RAM launcher

You should also move the midship liferafts. True, they are encased in fire retardant glass fiber, but they still won't like being bathed in rocket exhaust every time you fire a missile.

I may well re do the Gemstone, I need to to batches I and II as well and with the feedback and whatnot I've been getting for the corvette, hopefully they might be more believable.

Hugely WIP so colours etc are all temporary, as a layout in general what's the verdict? (Ignore the batch 3 in the template for now) Batch 1 will be GP vessels, Batch 2 will be AA orientated vessels and Batch 3 will once again be GP vessels
  • 127mm quite far forward of the bridge, RAM type CIWS in the gap between the two areas on the forecastle, VLS behind that
  • Aft of the bridge SSM / AShMs (non VLS)
  • Aft of the funnel, SVTT possibly?
  • CIWS mounted atop the hangar structure, possibly with some small calibre guns (7.62 or 12.7mm)
  • Hangar capable of taking an WS-70 and two MQ-8Bs ortwo WS-70s

I know I'm going to have to change the profile of the bow and associated bits to make it less wet because as of now it just doesn't look right.

What do you guys think of the draft for this I'm not sure it looks proportionate myself, compared to the last iteration of the gemstone...
