The Corrán-class Offshore Patrol Vessel is SDY's newest patrol vessel for long-range patrols from ports with relatively little in the ways of harbour infrastructure, although it of course profits from said infrastructure. It is a police and coast guard vessel and less a military vessel.

The term corrán means sickle or hook and is the name of a character in the TV-show Marla, a Bad Boy with a Golden Heart, who more often then not finds himself on the side of the titular heroine and is hotly tipped as her love interest.

Design

The Corrán-class Offshore Patrol Vessel is a classical monohull-design of steel. Due to high automization of the vessel's systems, the Corrán-class Offshore Patrol Vessel can be crewed by 44 sailors, plus carry a boarding team of ten soldiers, including a dinghy. The entire crew is provided with comfortable accomodations, including a small recreation room and wider bunks. An onboard cell can house up to four prisoners, but has space for eight (it might get a bit cramped).

Due to its relatively shallow draught, the Corrán-class Offshore Patrol Vessel can also operate on larger rivers and lakes.

The Corrán-class Offshore Patrol Vessel is, like many of SDY's newer designs for military and law enforcement, designed with a reduced radar crosssection, but not a dedicated stealth-vessel. Radar-absorbing materials are used with the superstructure, many flanks being inclined, with all facilities like the anchorhouse or stairwells inside of the superstructure.

The acoustic signature is reduced as well by resting the diesel generators on shock absorbers. This also serves for the comfort of the crew, as this also reduces the noise on board.

The Corrán-class Offshore Patrol Vessel has no aviation facilities bar a landing pad for a light helicopter, but no hangar. The flight deck is rated to handle vectored-thrust VTOLs if necessary.

Besides that, the Corrán-class Offshore Patrol Vessel is equipped with a catapult for launching and a small crane for recovering medium seaplane drones, as well as with a workshop to maintain them, as well as the facilities to recharge electrically powered drones and to refuel fuel powered ones. Launched via catapult, the drones can be used for reconnaissance, research, attack and a variety of other missions. The drones are recovered via net-landing.

The Corrán-class Offshore Patrol Vessel can carry up to four medium drones. Besides fixed-wing seaplane drones, helicopter drones can be carried.

For the detection of transmissions, as well as their interception, identification and location of sources of electromagnetic energy for immediate reconnaissance and threat recognition, as well as long-term planning of operations. The system also provides the capability to provide Signals Intelligence, namely by recording and decoding radio transmissions, as well as the decoding of simpler codes.

Sensors and Processing Systems

The Corrán-class Offshore Patrol Vessel is equipped with one combined Air/Surface Search Radar, which doubles as a navigation and fire control radar.

The Nuacht N-12 Mark III Air/Surface Search Radar (Multi-Function) is a cheap and easy to operate system, capable of tracking 350 targets at maximum in TWS-Mode, from missiles to passenger planes to small fast attack craft, and to track own fire for adjustments just as easily.

The Corrán-class Offshore Patrol Vessel is equipped with a small weather forecast suite, which can be used as a mobile weather station to make accurate forecasts. As such, the crew of the Corrán-class Offshore Patrol Vessel can plan operations with more and more accurate information.

Armament

The Corrán-class Offshore Patrol Vessel is a heavily armed vessel, primarily due to its Túirín T-12 Mark II Turret with two 76mm main guns. While the armament seems excessive, it is with good reason as more and more criminals and pirates make it necessary for law enforcement agencies to have heavily armed vessels at the ready. The Túirín T-12 Mark II can be used as both an anti-surface gun, for shore bombardement, as an auxillary anti-air gun for self-defense and, of course, for intimidation. With its maximum firing range of 27.5 kilometers and due to its positioning at the bow, it can use the complete range of its traverse, 160 degrees to either side, it is a threat to any enemy in any situation.

For more dedicated air defence and multipurpose-gunnery, where a 76mm gun might be a bit too much, the Corrán-class Offshore Patrol Vessel carries two Ceantar C-44 Mark II 40mm guns, originally marketed as AA-guns, but more like multipurpose guns. With one to port and one to starboard, the C-44s carried by the Corrán-class Offshore Patrol Vessel has a wide traverse for all-round protection.

As a less lethal method to dissuade an attacker from the Corrán-class Offshore Patrol Vessel or its wards, the vessel is armed with two water cannons with a throughput of 1200 litres of water per minute (seawater pumped aboard from beneath the vessel), with ten bars of pressure and a range of 65 metres. These guns, one on port, one on starboard, can also be used as deluge guns, including a function to spray firefighting foam.

Additionally, the Corrán-class Offshore Patrol Vessel's Superstructure has four balconies, positions on which additional weapons or heavy weapons teams can be posted.

History

In 1998, the SDF-Navy searched for a cheap and reliable patrol vessels to protect the shores of the Free Lands from foreign illegal fishermen, smugglers and similar fiends, which resulted in the Fiagai-class Patrol Vessel, a small sloop in the tradition of the Miodóg-class Sloops. The first vessels were commissioned in 2004, working as coast guard and with the customs authorities, as administrative assistance, as well as keeping the trading routes safe, in other applications working as testbed vessels, tugs, radar pickets and other roles.

Around the same time, the Water Polices of the Free Lands searched for replacements for their ageing fleets, belaying a decision further down the road until 2014, some deciding to acquire Fiagais from the SDF-Navy, which were handed down from dissolved Patrol Gunboat Squadrons in the Naval Reorganization of 2016 (three boats found a new, loving home that way). Others decided around that time to approach Silverport Dockyards Limited with a Request for Proposal – the Corrán-class Offshore Patrol Vessel, less a military vessel and more a police vessel, also intended for the export market.

The first five units, sold to the Water Polices of Wembury, Tipa and Geata, were named Corrán, Stuama, Dubh, Marla and Gríosóir, all of which are characters of the aforementioned TV-show, Sicín Studios sending delegations to the commissioning ceremonies in 2017 and Corrán's Voice Actor, Finnegan Aisteoir of the Tribe of Wexford, a Servant of Gavida, holding the speech and devoting the vessel to its purpose.

In 2018, four boats of the class were deployed as part of the Anti-Piracy Operations off Frozopia.
