The Endurance-class (Daoan: Sức chịu đựng) multi-mission frigates is a class of frigates in service within the Daoan Congressional Republic Navy designed, developed & constructed by Bao Marine and its subsidiaries. The Endurance-class is a development of the earlier Independence-class frigates, a lighter guided-missile frigate weapons platform. Aside from the standard anti-aircraft, anti-surface and anti-submarine warfare roles, of which the Independence-class were built for, Endurance-class frigates are able to fulfill a wider variety of mission profiles ranging from amphibious warfare and numerous other military operations other than war such as search and rescue, distribution of humanitarian aid, anti-piracy, counterterrorism and many more. The Endurance-class's versatility is largely owed to its enlarged capacity with it being 20 meters longer and 5 meters wider than the Independence-class. The extra space onboard the Endurance is capable of accomodating a large troop complement, up to 150 marines or a company's worth alongside a large cargo bay where variety vehicles such as motorized, armored fighting vehicles and landing crafts can be stored and deployed when required. Ships of the class have a small ramp with suport systems that act as a small well deck where its fleet of smaller landing or assault crafts can egress and ingress with ease. Vessels of the class are able to accomodate up to two medium helicopters and three unmanned aerial vehicles in its helicopter deck & hangar facilities. The type of vehicles or smaller craft that the Endurance carries can be easily changed to suit an Endurance's specific mission profile. The Endurance-class's role as a troop transport without sacrificing its firepower was purpose built for the Daoan navy where it requires more and more multi-mission vessels as to compared to larger and heavily specialized or dedicated vessels such as destroyers and helicopter carriers. The Daoan navy has ordered three Endurance's to replace one of its ageing Dammay-class landing platform docks with the first ship, the TCD <INSERTNAME> commissioned in 2020.

Design

Electronic Warfare

The Endurance-class is equiped with suite of sensors & processing systems that allow them to fulfill a variety of roles. Ships of the class are equipped with RAS30 PESA 3D air & surface radar, originally developed by Mach Aerospace and adapted for use in the Daoan Navy. The RAS30 PESA radar is able of detecting & tracking hundreds of surface & air targets simultaneously with a high refresh rate. It is capable of providing mid course updates to both active and semi active surface-to-air & anti-ship missiles launched from the frigates. The RAS30 AESA radar is composed of a series of computer controlled phased array antenna arrays, with each antenna array having their own solid-state transmit-receive module (TRM). This allows the RAS30 to produce many beams at different radio frequencies simultaneously, a significant improvement over the navy's older passive electronically scanned array (PESA) based radars which is only capable of emitting a single beam of radio frequency. The RAS30 AESA radar has a higher resistance to jamming and low probability of intercept by hostile radar warning receivers (RWRs). Fire control for the ship's suite of weapon systems is provided by the TK-4 fire control system. The frigates are equipped with the LS-9 secondary surveillance radar (SSR) as a backup radar system. For anti-submarine warfare Independence-class frigates are equipped with hull-mounted SNR-360 active/passive sonar array developed by Bao Marine. The SMART Mk.30 Combat Manage System serves as the vessels' primary combat information center.
