The Bartoloměj class is a class of guided missile cruisers designed and built by the Milsau Shipyard and Mostky Shipbuilding. The class is named after King Bartoloměj III, ruler of Holynia from 1731 to 1757. 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 Mladkov class cruisers and complement the Podkost and Kováň class guided missile destroyers.

Development

The Mladkov class cruisers suffered from limited air defence capabilities. The limited air defence radars and low anti-air missile stocks of the Mladkov class became apparent when the Lapša class guided missile destroyers entered service. Growing maintanence issues on systems, weapons and the powerplants of the Mladkov 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 Mladkov 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 first ship was to be named after King Bartoloměj III, ruler of Holynia from 1731 to 1757. The ship was launched in 2016 and conducted sea trials in 2018. Fitting out of the King Bartoloměj III 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 Lapša class are guided missile destroyers serving in the Royal Holyn Navy. The class features a fundamental upgrade of anti-air capabilities with a 3D air search radar and 48 (6 x 8) VLS cells with the PS-105M surface to air missiles. The Lapša class was intended to consist of 15 ships, but the fall of Communism in Holynia and the resulting economic crisis only led to 3 ships being built. The class was succeeded by the Podkost class guided missile destroyers.

Development

The Lapša class destroyers, known then as Project 190 began development in the early 1990s as the Holyn Navy sought a replacement for the Eule and Slavníč classes of destroyers. A single unified platform was intended to reduce costs, but with dedicated anti-air and anti-submarine variants. Design work was completed in 1991 by Ploska Shipyard. Initially, steam turbines were considered for the class, however, modernised gas turbines from the Slavníč class were added to the design. Four gas turbines would output 120,000 horsepower (89 megawatts). In July 1991, design work on the VLS cells was completed. Initially, two batches (fore and aft) of 48 revolver style VLS cells were planned. The helipad would have a sliding deck with VLS cells underneath. Cost and reliability concerns led to the aft VLS cells being deleted in the final design. Two fore 100 mm cannons were planned in a similar fashion to the Slavníč class, however this was reduced to one sole 100 mm cannon.

15 ships were planned for the initial batch of destroyers. The design incorporated 48 VLS cells with the maritime variant of the PS-105 surface to air missile, PS-105M. The first ship was laid down on 15 November 1992 by Ploska Shipyard. The Lapša was launched on 30 August 1993 and finished sea trials in February 1994. She was commissioned on 4 December 1994. One hull was laid down in 1993, the Jazernica which was launched in June 1994. The third ship of the class Sazdice was laid down in late 1994. Jazernica was commissioned into service on 8 March 1996 and Sazdice was scheduled to be commissioned in 1997. Four more hulls were laid down with plans for them to be commissioned by 2000.

The political and economic crisis that griped Holynia between 1997 and 2001 greatly affected the Lapša class. Sazdice was moored in Slatnik at 99% completion. The Holyn government pulled all funding for the remaining four hulls, which were at various stages of completion. Kosmo, the fourth ship of the Lapša class was at 60% completion. The shipyard was unable to complete the ship as a result of funding issues. Ploska Shipyard soon became clogged with various damaged civil and warships from the war in Bogoria. In June 1999, the Ministry of Defence decreed that Sazdice would be commissioned in 2000 and Kosmo would be completed. In 2000, work began on Sazdice and the ship was commissioned in April 2000. Funding issues resulted Kosmo and the three other unfinished hulls were cancelled and began to be scrapped.

Weaponry

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.
