The Silný class is a class of guided missile cruisers designed and built by the Milsau Shipyard and Mostky Shipbuilding. The class is named Silný, the Hornat and Masov word for strong. The class is designed to have a multi role functionality. Its primary role will be to operate as a command ship with anti-ship, anti-land, anti-submarine, and anti-aircraft capabilities. The class also has ballistic missile tracking capabilities because of the multifunction active electronically scanned array naval radar system. The class is meant to replace the Víťazný class cruisers and complement the Podkost and Ledetz class guided missile destroyers.

Development

The Víťazný class cruisers began showing their ageing air defense capabilities. Growing maintanence issues on systems, weapons and the powerplants of the Víťazný class led the Holyn Navy to research a replacement. In 2012, Milsau Shipyard and Mostky Shipbuilding were awarded a contract to develop the replacement of the Víťazný class. The development was alongside the Ledetz class guided missile destroyers, which the new cruiser would share a number of similar features. The design was unveiled in 2014 with construction beginning in 2015. The ship was launched in 2016 and conducted sea trials in 2018. Fitting out of the Silný concluded in 2019 and the ship continued sea trials and training. The ship was commissioned on 10 March 2021 and entered service with the 3rd fleet.

The second and third ships were laid down in 2018, with Zdravý being launched in 2022 and Pevný being fitted out as of 2024. The fourth ship of the class, the Rázny, is in early stages of construction. Zdravý joined the 1st fleet on 4 January 2024.

Design

Propulsion

The Silný class is powered by six 5 MW turbine generators, providing substantial electrical power to the ship’s systems. For propulsion, the destroyers utilize four 28 megawat Combined Gas and Gas (COGAG) turbines, enabling a maximum speed and a range of approximately 5,000 nautical miles. This propulsion system allows for efficient cruising as well as rapid response capabilities in diverse maritime environments.

Electronics

The Silný class is equipped with a sophisticated electronics suite designed for enhanced situational awareness and combat readiness. The primary radar is the R5661-A Active Electronically Scanned Array (AESA) 3D radar, which provides long-range tracking and targeting capabilities. Additionally, the vessel is outfitted with X-band radar for surface search and target acquisition.

The destroyers feature an advanced electronic warfare system capable of electronic surveillance and countermeasures, enhancing the vessel's survivability against threats.

Armament

The ships are armed with a single 130 mm naval gun, suitable for engaging surface targets and providing naval gunfire support. For defense against incoming missiles and aircraft, the destroyers are equipped with a CIWS, offering rapid-fire capability to intercept threats at close range. The class feature a 24-cell short-range Surface-to-Air Missile (SAM) launcher, as well as 112 Vertical Launch System (VLS) cells that can fire a variety of missiles, including surface-to-air, anti-ship, and land attack missiles. Two sets of torpedo launchers are integrated into the design, allowing the vessels to engage submarines and other surface threats effectively.

The Podkost class are guided missile destroyers serving in the Royal Holyn Navy. The class introduced active electronically scanned array (AESA) radars into navy service. Seven ships were built between 2004 and 2017, with the class being suceeded by the Ledetz class of guided missile destroyers. The Podkost class is the first class of the Project 250 destroyer design.

Development

Research into building new Lapša class destroyers was conducted in 2002. The Ministry of Defence decided to begin with a new clean sheet design to succeed the Lapša class. A contract was awarded to Milsau Shipyard to design and construct a new class of destroyers for the Royal Holyn Navy. The first keel was laid down in July 2004 at Milsau. Ground tests of many of the systems were held by the various subcontractor companies between 2004 and 2006. The first hull was launched in March 2005 during a ceremony attended by the Royal family. It was the largest naval ship to be launched in Holynia since 1997. Fitting out of the ship continued throughout 2005 and sea trials began in 2006. The new active electronically scanned array (AESA) radar system was tested in early 2007. Work was concluded in mid-2007 and the first ship, HMS Podkost was commissioned into Navy service in May 2007. 3 further hulls were laid down between 2005 and 2009. The first ships in service succesfully demonstrated their data link capabilities when completing air defence exercises in the Holyn Sea.

Design

Weapons

The surface to air missile of the Lapša class is the PS-105M (maritime) air defence missile launched from 48 revolver style vertical launching system cells. The FS-610 are the primary land attack cruise missiles. The anti-ship missile is the FS-500 supersonic anti-ship cruise missile. The typical loadout prioritises carrying more PS-105M anti-air missiles over the other surface to surface missiles. This can be altered depending on the specific mission.

A single fore mounted 100 mm gun is mounted on the Lapša class ships. Two OS-150 CIWS provide defence capabilities at close ranges.

Command and control

The class featured the first generation of the Hodit command and control computer system developed by the Uhrov Polytechnical Science Academy. The system uses the ship's 3D air search radar to track targets and assist naval personnel in target identification and area air defence. It enables the PS-105M missile system to engage multiple targets simultaneously. Hodit was designed to communicate with the PS-105M to provide guidance and intercept scheduling. During the 2016 refit of the Lapša class, Hodit was updated to Hodit IV standards.

Radar

A passive electronically scanned array E band 3D radar is mounted on the ship for air target acquisition and is linked with the Hodit combat system. The radar can search for aircraft up to 300 km. Much of the remaining systems were carried over from the Eule and Slavníč destroyers. A G/H band surface search radar provides scanning for the CIWS system. An over-the-horizon targeting radar is mounted for surface search. Navigation and surface control radars are also mounted.

Sonar

The powerful anti-submarine warfare systems of the Slavníč class was installed on the Lapša class. Hull mounted and towed array sonar systems are installed on the Lapša class.

The Royal Holyn Marines (Hornatyian: Kráľovský Holynske Mariňákov), or Marines (Hornatyian: Mariňákov), is the amphibious warfare branch of the Royal Holyn Defence Forces. Originally part of the Holyn Navy as the Holyn Naval Infantry, the branch became independent from the Navy in 2003. This saw a significant expansion in the size of the Marines. It consists of 45,000 active personnel, supported by 20,000 reserve personnel. The Royal Marines is made up of five brigades capable of combined arms operations and supporting regiments of aviation, combat engineering, and artillery. The Royal Holyn Marines, along with the Holyn Airborne Assault Forces comprise the quick reaction forces of the Holyn military.

History

Holyn Kingdom

On July 22, 1721, the Naval Regiment was formed by the Holyn Admiralty as the land regiment of the Royal Holyn Navy. The Regiment used the rank structure of the Navy and was led by Naval officers. It was largely a temporary force, only being formed prior to specific naval operations. It would be made up of sailors transferred from ships and other units. It was often thought of as a demeaning and often unpopular unit to be assigned to. In 1761, the Naval Regiment increased to Corps size, totalling roughly 40,000 sailors and officers. It The force attained the official name of Naval Infantry Corps in 1764. During the 10 years war in Spero, the Navy Infantry conducted little to no amphibious operations, instead fighting alonside the ground forces as regular infantry. The Navy infantry during this time expanded, becoming a permanent force within the Navy. The Naval Infantry was instrumental in Holynia's expeditionary operations in Navron during the 19th century. Along with armed units of privateers hired by charted trading companies, the Naval Infantry participated in the seizure of north western Navron in 1824. Aside from its land operations, the naval infantry was tasked with guard duties of officers and enforcing order among sailors. In 1859, the Naval Infantry converted from Naval enlisted ranks to a rank structure mirroring the Holyn Army. Officers retained a Naval like structure, but suffered from a lower status in comparison to a full-fledged Navy officer.

In 1917, the Naval Infantry was an instrumental force for the Holyn government during the Great Spero War. Several succesful landing operations were conducted in western Spero which allowed the Central Alliance to gain the upper hand towards the end of the war.

During the Holyn Civil War in 1927, the Naval Infantry remained loyal to the monarchy. Despite several defections, the Naval Infantry were one of the last forces left fighting for the Monarchy in Holynia. Naval Infantry troops were tasked with the defense of Slatnik, the temporary residence of the Royal Family. They provided security during the Great Escape of 1927, when the Royal Family, most of the loyalist troops and wealthy individuals, fled to the overseas Holyn territory of Skoskie. Roughly 1,000 Naval Infantrymen remained behind and waged an insurgency in southern Masovia until mid 1928. The routed Loyalists rebuilt their forces in Skoskie, including the Naval Infantry. The Communists did not field a Naval Infantry force in the early years.

Holyn Socialist States

In 1943, the 37th Naval Rifle Regiment was formed in Slatnik by orders of the Holyn Navy Commander, Admiral of the Fleet Jakub Kočiš. This constituted the first Naval Infantry regiment in Holynia since 1927. A second regiment was formed in Plotny in 1945, the 40th Naval Rifle Regiment. Two more Naval Rifle Regiments were formed in 1946. In 1947, the 7th Naval Infantry Division was created. Shortly after the 7th Naval Infantry Division was formed, the Holyn leadership decided to support the overseas communist rebellion in Salcheny, a colony of Pamtoria. The 37th Naval Rifle Regiment and 53rd Naval Rifle Regiment were deployed in support of the rebellion, arriving in Port Vola on 17 September 1947. These troops spearheaded an assault on pro-Pamtorian positions, effectively handing victory to the Salcheny communists. The 37th and 53rd Naval Rifle Regiments both received the honorific title of Guards, and the Order of the Red Carnation, as a result of their actions in Salcheny.

In 1951, all Naval Infantry Regiments were reformed simply as Naval Infantry Regiments, removing the Rifle designation. The Naval Infantry increased in size during the 1950s, largely to support foreign expeditionary operations in Navron. A rivalry formed during this period, as the Holyn Airborne Assault Troops, the other shock force troops of the Holyn military, began to similarly increase in size. In 1951, the Naval Infantry and Holyn Airborne Assault Troops both supported the communist revolution in Movargovina.

The Navy introduced several new landing ships in the 1960s, representing a major step forward in capabilities for the Naval Infantry. A reorganization of the Naval Infantry took place in 1972. All regiments were transformed into brigades, and the 7th Naval Infantry Division became the 7th Naval Infantry Corps. This was part of a broader push to reorganize the Holyn military. However, in 1975, Defense Minister Oliver Rušil abandoned these plans and reverted the 7th Naval Infantry Corps back into a Division. Brigades reverted back into regiments. The reformation plan largely affected command staff, rather than front line personnel.

Throughout the 1980s, the Naval Infantry gradually expanded their capabilities. They adopted new vehicles such as the BVP-2 infantry fighting vehicle. The Holyn Navy began development of a landing helicopter dock/amphibious assault ships, Project 1600 amphibious assault ships. These ships would be able to carry up to 1,000 naval infantrymen and 40 armored vehicles.

During the Bogorian War of Independence, the Holyn Naval Infantry were heavily involved in the fighting. Operational groups of the Naval Infantry were present in the Battle of Pavířov. A battalion of the Naval Infantry were also present in the Battle of Gniewkowo.

Second Holyn Kingdom

The Naval Infantry saw great setbacks during the early 2000s. Funding decreases, combined with losses during the Bogorian War, resulted in a reduction in size and scope of the Naval Infantry between 2000 and 2002. In 2003, the Ministry of Defence announced the Naval Infantry would become a seperate troops branch, similar to the Airborne Assault Forces. To coincide with this, the Naval Infantry were renamed the Mariňákov or Marines.

Aside from the name change, organizational and rank restructuring took place. The Marines replaced the last vestiges of Navy ranks, introducing Officer ranks similar to the Ground Forces. Similar to the other branches of the Holyn military, a non-commissioned officer academy was established, based off the Ground Forces. The Marines were the first branch to end conscription in early 2004. The Marines were designated the branch which would serve as the baseline for all other services in the Holyn military. The non-commissioned officer academy began training the first Desátníks in late 2004. The culture shift in the Marines became evident in late 2005, during the Bogorian Border Crisis. The Holyn Marines were able to effectively operate independently and achieved a higher amount of succesful operations.

In 2008, the Marines added their first tank units, a battalion each of main battle tank units to the 37th Guards and 53rd Guards Marine Brigades. Additional tracked armor vehicles were introduced during the 2000s and 2010s to increase the firepower capability of the Marines.
