The Skjold MOD corvette is LRR's most advanced small coastal patrol vessel. It is crewed by 20, and can reach a maximum speed of more than 100kph. Its surface effect/catamaran hull design, while giving it a high speed, also gives it extremely low draft and extremely low ground pressure, making it near-impervious to pressure-sensitive sea mines and granting access to shallow coastal waterways. It is of 90% composite construction, which serves to further deduce the ship's radar cross-section, as does its stealth design features. It is an excellent patrol/missile ship.
Propulsion
The Skjold MOD is propelled by two common LRR hybrid gas/electric drive systems for redundancy. The two turbine/generators are placed side by side, and are not all that large or heavy.
This propulsion system offers a very high redundancy and exceedingly long endurance, as well as environmental friendliness (it is not only a missile boat, but a fisheries protection, SAR, and coast gaurd craft) and a low thermal signature. The low thermal signature coupled with the stealth design features incorperated into the Skjold allows the craft to sneak around, avoiding air and radar detection. The low noise signature when running on electric drives also makes it harder for submarines to detect the Skjold. The positioning of the waterjet nozzles gives the Skjold very high manouverability at speed, akin to thrust vectoring in aircraft.
Hull Design
The Skjold class has a unique hull arrangment, shared only with the russian Bora class corvettes. Instead of a more conventional single-hulled or hydrofoil design, the Skjold relies on a catamaran surface effect design, basically a combination of a catamaran-hulled vessel and a hovercraft. The catamaran hulls alone would give the Skjold a high speed. This coupled with the air-cushion system between the hulls allows the Skjold to reach a maximum speed of over 100 kilometers per hour.
The hull design is inherantly stable, so massive amounts of computers are not needed to keep the craft steady. With a low draft and ground pressure, coupled with more than 90% composite construction, the Skjold is almost impervious to mines. The low draft allows the Skjold to operate in shallow, coastal waters where conventional craft would not be able to go, allowing it to be maintained on the beach- literally. The Skjold is able to get in along the coast, finding cover that would be unavailable to a conventional vessel of similar size and function.
However, due to the flat hull design, the Skjold cannot self-right itself. The Skjold MOD has excellent seakeeping nontheless, and only the most severe waves could topple it.
Key Design Features
The Skjold MOD has been made so major components are interchangable with other LRR-make ships.
The ship overall has been made as easy to repair as possible, with big access panels and high redundancy overall.
Radar, Sonar, & Countermeasures
The Skjold is equipped with a multipurpose surface/air radar that can detect stealth (moving fast) and conventional air targets at more than 180km. It can identify and track at 100km.
The sonar is an advanced system, used to aim the vessel's two torpedos, user-customizable.
An IR and night vision system are both included in the Skjold's sensors package, for the ultimate passive operation.
The Tactical Radar Surveillance System (TRSS) provides Electronic Support Measures (ESM) and Radar Warning Receiver (RWR) functions. The system's 360° circular array interferometer antennas can detect air and surface threats.
Skjold vessels will be equipped with the MASS (Multi-Ammuntion Softkill) decoy system. MASS can launch up to 32 omni-spectral projectiles in a time-staggered configuration against anti-ship missiles and guided projectiles.
Weapons Systems
The Skjold carries eight anti-ship missiles, the standard type being the NSM anti-ship/land attack missile with a range of over 150km. The vertical launching apparatus can take a wide range of missiles, though.
For anti-aircraft defense, the Skjold carries four SA-20 medium-range missiles, modified AA-11s with a 40km range. They are carried in their own VLS tubes in front of the ASMs.
The Skjold carries a 57mm rapid-fire cannon in the foreward turret. The L&F Goalkeeper III is the most advanced LRRN CIWS system, in that it is more like a milennium gun as opposed to the 30mm minigun systems more commonly used. The 57mm gun can fire 300 rounds per minute, and fires fragmentation projectiles which have been shown to be more effective against missiles than high-rate 30mm fire. The gun can engage targets traveling at speeds up to mach 5 and at ranges out to 14km. The Goalkeeper III is also useful as an anti-ship weapon.
Cost: 105,000,000 USD For Full Version
60,000,000 for de-missiled version with 76mm super-rapid cannon

The Tern class Offshore Patrol Vessel is meant to be an extremely versatile SAR vessel for the LRRN.
Propulsion
The Tern is powered by two hybrid gas/electric turbines, the same as on the Skjold MOD. Since the Skjold MOD has very little water resistance, the same power can obviously make it go faster, but the Tern can still manage a sprint of 33 knots.
Radar, Sonar, and other detection systems
The Tern is equipped with an advanced surface search and weather radar, made to pick out ships and very small objects such as rafts up even in very high seas, as opposed to the combat radar on the Skjold. The Tern's radar has a range of over 100km, and can pick up even the smallest one-person raft in very adverse conditions.
The radar is complimented by a thermal imaging system, used to pick up smugglers and rafts in high seas and other adverse conditions at close range.
The Sonar is used primarily as an echo sounder, but can be used to track submarines as well.
Hull Design
The Tern is designed for maximum seaworthiness in the most dangerous weather conditions. It can right itself once capsized, and bulkheads can withstand extreme pressure. The windows are made of thick, bulletproof glass to help cope with the pressure of a capsize. Some Terns have a bowl-shaped hull for arctic operations, but most have the more conventional hull design.
Weapons Systems
Being primarily a SAR and coast gaurd ship, the Tern only carries light armement. Two 20mm MGs are mounted, one on the bow and the other behind the helipad. 12.7mm and infantry-caliber weapons are also carried, but not necessarily mounted.
Other Systems
The Tern can act as a towship with its large crane behind the helipad. It is also fully outiftted to be a fireship, with two high-presssure nozzles above the bridge.
The Tern is also equipped with oil spill containment gear.
Helicopter and Boat Capacity
The Tern can carry any helicopter up to Sea King size, and comes standard with a pair of RIBs for boarding and handling of the surface skimmers during oil spill containment.
Cost: 80,000,000 USD

The Hauk class patrol boat is an excellent coastal patrol vessel. It can operate in the harshest of environments and from the most primitive facilities.
Propulsion
The Hauk is powered by a L&F hybrid gas/electric drive system, which gives the boat a maximum speed of 34 knots all-out.
The hybrid gas/electric system not only makes the boat environmentally friendly and fuel efficcent, but also gives it a very small thermal signature. This allows the Hauk to sneak around very well.
Radar, Sonar & Countermeasures
The Hauk is equipped with a multipurpose search/track radar much like that on the Tern. It has a maximum range of over 120km, and can track stealth.
IR cameras are also included to aid in the aquisition of targets at close range and in passive conditions.
The Hauk is equipped with a basic sonar to allow it to aquire submarines. It is, as previously stated, a basic sonar, but it gives the Hauk at least some anti-sub utility.
The Hauk is equipped with a good countermeasures suite, consisting of an IR missile blinder, and chaff, flare, and IR decoy launchers. This system can down most modern ASMs on paper.
Hull Design
The Hauk, being an older design, consists of an all-metal welded hull with bridge and deck structures made mostly out of composites.
The hull is a conventional design, but hydrofoil legs have been added to LRRN models to increase speed.
The hull is tough and simple, and is designed for the worst weather conditions.
The Hauk can right itself once capsized, due to the hull ballast. The ship's internals are made strong, and if most of the bulkheads are closed at the time of the capsize, the ship itself should be in no danger of sinking. The bridge windows are made of thick, bulletproof glass, as much to deflect bullets as to withstand the high pressures exerted on the windows by wave action.
Weapons
The Hauk carries a single 40mm cannon as its main weapon. It has a maximum range of around 3km, and can pierce tank armor. The gun is housed in an armored tub which can withstand 20mm rounds.
Two SA-23 SAMs are carried as air defense weapons. They are launched from an armored tub behind the bridge, evolutions of the Mistral shoulder-launched SAM. They can be dismounted from the ship and brought on land, and have a maximum range of 6km. The SA-23 is a fire-and-forget weapon.
The Hauk can carry two RBS-15 ASMs in stern launchers as well. The RBS-15 Mk. 3 has a maximum range of over 200km, giving the Hauk formidible striking power.
Two 12.7 or 7.62mm MGs can be mounted on the bridge and on the stern.
Other Systems
The Hauk can carry a unmanned submersible vehicle on board, used to locate and destroy mines. The Hauk also carries a RIB immediately aft of the bridge.
