The Robert Byrd class is being developed off the Visby class as a high-speed multirole patrol vessel to replace the Bora II. While it will be signifigantly slower than the Bora, topping off at 35 knots, it is stealth and can carry a helicopter. The Robery Byrd is worthy of replacing the nigh-legendary Bora II because, first of all, the Bora II hulls were getting a bit aged.

The Robert Byrd is a heavy combat vessel, easily the size of a Duke class frigate. It is designed to allow


Powerplant

The Robery Byrd is powered by a Lunkwill&Fook Hybrid gas/electric system, the same as on the Bora II. The seagoing hybrid system offers many advantages over more common propulsion systems.

The Byrd can cruise almost indefinately at low speed on its electric turbines, which recharge as water passes into a generator apparatus near the stern. (This function can be turned off for quieter running.)

While the electric powerplant cannot by itself provide combat speeds, the diesel side of the hybrid system gives the Byrd the ability to make sustained high speeds without the risk of going dead in the water.

The hybrid system, coupled with the Byrd's low-observable construction, makes the ship very difficult to detect when running on electric power, which has a much smaller thermal footprint than combustion powerplants. The hybrid system supplies a maximum sprint speed of 37 knots and a sustained speed of 30 knots.

Sensors&Countermeasures

The Robery Byrd is equipped with a modified Bora II radar, and a top-of-the-line sonar suite. The Mk.81 search radar is capable of detecting targets at a range in excess of 170km, extended out to at least 300km with the use of a spotter helicopter or drone. The Mk.81 can detect fast-moving stealth objects as well, since the radar processing system looks at speed more than size. For example, a really fast contact, even if it is very small, will be interpreted as a stealth threat as would a normal, non-stealth contact. This, of course, means that at long range stealth helicopters can get by the Byrd, but that defect is the same for most radar systems.

In addition to the radar systems, the Byrd is equipped with a comprehensive thermal imaging system for detecting and tracking close-in and small targets, things that the radar would possibly overlook (such as smuggling boats).

The Byrd's sonar can pick up and categorize even the faintest undersea noises without giving away its position by using active sonar in the detection phase.

RWR and IR missile detection systems are all included in the countermeasures package, as well as a 30mm Goalkeeper II CIWS which can detect missiles at 30km and engage them at 7km.

Softkill systems and IR decoys are all included as well. The total countermeasures package gives the Byrd nigh-unparalleled survivability.

Weapons Systems

The Robert Byrd is a very heavily armed vessel. It has 10 vertical launch cells for SAMs, and 8 horizontal launch cells for ASMs, such as the RBS-15 and Konsberg NSM. The Robery Byrd carries 4 400mm torpedos with active homing or wire guidance stored in internal tubes. The torpedo option is fully customizable in order to fit user preferences.

The Robert Byrd is equipped with a Goalkeeper II 30mm CIWS system mounted on the stern, in back of the helipad. There is also a 155mm rapid-fire howitzer mounted in a turret behind the bridge, close to the helipad to allow for easy helicopter re-loading. The lightweight M777 howitzer is equipped with heavy shock absorbers to dampen the howitzer's recoil to an almost non-noticable level. In addition to the 155mm howitzer, the Byrd mounts a reduced LAR-160 rocket launcher behind the 155mm howitzer. This rocket launcher can be used to engage both land and sea targets, and the type is common on LRRN vessels.

Helicopter Capacity

The Byrd class vessels can carry a wide variety of medium-sized ASW helicopters, such as the Panther, Ka-29, and Kaman Husky. Attack helicopters such as the KA-50 series and tiger-sized craft can operate off the Byrd as well.

NOTE: Larger helicopters such as the Sea King, Mi-8, Merlin etc. can set down, but it is unsafe to operate them from the Byrd.

Helicopters give the Byrd enhanced ASW capability, as well as an airborne radar platform, and the ability to conduct SAR, anti-ship, anti-tank, and tactical transport missions long distances from coastal waters.

The Halifax-class frigate forms a large part of the LRRN patrol fleet. It has the major function of providing long-range offshore ASW in protection of merchant convoys around the bering sea area.

Propulsion

The Halifax-I is powered by two combined gas/electric turbine assemblies, LRRN frigate standard. The propulsion system is roughly the same as on the Byrd, so for details see above.

The Halifax-I can reach a maximum speed of 31 knots.

Radar, Sonar & Countermeasures

The Halifax-I carries a multi-track radar with a range of over 150km, shorter than the Byrd, but still able to detect stealth and low-altitude threats.

As for sonar, the halifax-I is much better equipped than its more anti-ship oriented counterpart. The ship is equipped with a towed-array sonar and an on-hull sonar system, the two systems which can be used to look in multiple directions and listen more closely to undersea noises. This sonar system has a longer range and is more sensitive than the one on the Byrd.

The countermeasures system is a decoy launcher apparatus, geared towards launching chaff and IR decoys.

Ship Design

Being an off-the-shelf vessel, the Halifax is a relatively low-cost vessel, even with the advanced sonar. The hull incorperates some basic stealth features, but nothing special.

The Halifax-I has excellent seakeeping characteristics, meaning that it can withstand much poorer sea conditions than most other frigates. The Halifax-I is well-suited to the turbulent Bering Sea and North Pacific, the LRRN's backyard.

Weapon Systems

The Halifax-I carries two CDM combined missile-gun CIWS systems, one on the helicopter hangar and one above the bridge. The CDM is a combination of the Goalkeeper II 30mm and the RAM (rolling airframe missile) system. This combination gives the Halifax excellent anti-missile capability, which makes up for the lack of stealth features and the somewhat substandard countermeasures.

The I's main gun is an AK-176 176mm rapid-fire cannon, with a maximum range of 15.7km.

The I is also equipped with a BM-21 rocket launcher mounted foreward of the gun, which gives the Halifax-I serious anti-surface capability.

The I carries four NSM anti-ship missiles, and 10 SA-20 medium-range anti-aircraft missiles.

Helicopter Capacity

The Halifax-I can carry any helicopter up to the size of a Sea King in a fully-enclosed hangar.

Nice, but no Tartaros. The difference is, people will likely buy this....
(written at 4 in the morning by the bitter main/co designer of Tartaros. Any insult gleaned from this is only 1/4 intentional :P

On a more serious note, I like it. Nice amounts of detail, but I just bought a whole load of boats like these, so I don't need more.
That's a pretty big howitzer though, isn't it? If I'm wrong, I'm still using the 4 in the morning excuse.

155mm is a pretty standard artillery round, but I'll let it slide since you're tired.

Actually, he's right.

155mm is standard for NATO medium artillery, but only as pertaining to ground systems. However, as a naval gun, that would currently rank more toward the heavy category (medium naval guns are 100-130mm, and light are generally 57 or 76mm).

If this is even twice the size (in displacement) of the Visby, it's still way too small to be carrying a 155mm gun. You might be able to make a 155mm weapon for a 3000 ton frigate, but I wouldn't suggest it on anything short of a destroyer, do to issues with weight, recoil, and internal space. The visby would, if such a gun was on the bow, have a tendency to find her stern in the air (the projected weight for the 6.1" AGS is 95 tons, compared to the 620 for a fully loaded Visby). The recoil of a 6.1" gun would also be far too much for such a small boat to handle, and the act of firing alone could capsize her. Finally, with its size and so much internal space devoted to other essentials, you'd be lucky to have 2 minutes worth of ammunition. All in all, not a good choice.

If you look at the visby herself, she tops with a 57mm (2.25") gun. You might manage to go up to 76.2mm (3"), but I wouldn't go beyond that, as it's pushing the limit of what such a boat can hold.

OCC:

The actual production version has the 155mm placed towards the stern to compensate for the weight.

But it is not a heavy gun. Minus the wheels, weapons shields, and other stuff, the 155mm gun here is not a heavyweight weapon. Its like an M777.

This is a somewhat big ship. Significantly bigger than the Visby, frigate-sized at least. I'll fix it up and pitch it as a frigate I guess.

But yeah, it can't carry much in the way of helicopters and has a small crew, so while it is packed to the brim it works.

The Truittian Forces would like to purchase just two of these with the systems. 1billion USD?

Also, we are impresed at the detail you gave

Finally, I would like to ask:

Would any minor Modifications for more Truittian Friendly systems be allowed?

Also, how much would building rights of these cost (if you accept)

--Truitt

Cont.: Is it alright If I use the first picture as a picture for a naval Destroyer I am currently working on (it has very very different figures and are barley the same as this model).
Just that the whole thing is the best picture of a stealth vessal that size I have seen for a while that would fit some of the discription.

Try the French Lafayette class frigate.

But otherwise, your order is confirmed. This will be the bulk of your navy for about a month, you do realize.

I expected that you would say no.

Yes I am aware of its' power, I bought two becouse of one for defencive, and one for heavy offencive.

The money will be wired with pleasure.

Good doing buisness with you
