K130 Braunschweig Class Corvette

The K130 Braunschweig class (Korvette 130) is Germany's newest class of ocean-going corvettes. They supplement the Gepard class fast attack craft that are currently used.

They feature reduced radar and infra-red signature ("stealth" beyond the Sachsen class frigate) and will be equipped with two helicopter UAVs for remote sensing. Recently, the German Navy ordered a first batch of 6 Camcopter S-100 UAVs for the use on the Braunschweig class corvettes. Also the German Army plans to procure the Camcopter S-100 for land-based missions. The hangar is too small for standard helicopters, but the pad is large enough for Sea Kings, Lynx or NH-90s, the helicopters of the German Navy.

Originally the K130-class was supposed to be armed with the naval version of the Polyphem missile, an optical fiber-guided missile with a range of 60 km, which at the time was under development. The Polyphem program was canceled in 2003 and instead the designers chose to equip the class with the RBS-15. While the RBS-15 has a much greater range (250 km), the current version mounted on the ships, Mk3, lacks the ECM-resistant video feedback of the Polyphem. The German Navy has ordered the RBS-15 Mk4 in advance, which will be a future development of the Mk3 with increased range (400 km) and a dual seeker for increased resistance to electronic countermeasures.

Baynunah Class Corvette

The Baynunah class are corvettes for the United Arab Emirates' Navy. The lead ship is named after the Baynunah region in Abu Dhabi. Six ships are planned for this class. Sea trials are currently underway. Platform and combat systems trials are expected to continue through 2011, after which time the lead ship will be delivered to the UAE Navy.

This class is based on the CMN Group's Combattante BR70 design. The Baynunah class is designed for "patrol and surveillance, minelaying, interception and other anti-surface warfare operations in the United Arab Emirate's territorial waters and exclusive economic zone."

Kamorta Class Corvette

Kamorta class Corvettes are the Indian Navy's next-generation anti submarine warfare platform, built under Project 28. They are being built at Garden Reach Shipbuilders and Engineers (GRSE), Kolkata. The first corvette is expected to be delivered to the Indian Navy in 2012. All the four corvettes are planned to be handed over to the Indian Navy by the year 2014.

Project 28 is the primary project for driving indigenisation and developing the warship construction industry in India. The aim with this project is to stipulate unprecedented standards while providing opportunities to Indian vendors to develop expertise with the technology. The project, driven by the Navy's Directorate of Indigenisation, has been delayed by two years with a cost overrun from the originally estimated INR 28 Billion to INR 70 Billion, primarily to meet this goal.

The order for the first four corvettes was placed in 2003, with construction commencing on August 12, 2005.

The basic design for Project 28 was specified by the Indian Navy's Directorate of Naval Architecture, with the detailed design by GRSE. The design includes many stealth features, including reductions in noise and vibration of the vessels.

Displacing around 2500 tons and a length of around 110 metres, these vessels will have a very high percentage of Indian made equipment – either designed indigenuously or built under license through technology transfer agreements.

The DMR 249A hull steel is produced locally by SAIL (Steel Authority of India Limited). The main machinery is raft mounted to reduce acoustic and vibration signatures. Each gear unit and the associated engines will be mounted on a common raft. The vessel will feature automated control and battle damage systems. The Project 28 vessels use diesel engines built by Pielstick of France. DCNS supplied the noise-suppressing raft-mounted gearbox for CODAD propulsion. Wartsila India will deliver the low-vibration diesel alternators to power the on-board electronics. Other signature management control features are built in to combat the ship's infrared, radar-cross signature, noise and magnetic outputs. Two independent interconnected switchboards optimize redundancy and reliability.

It was announced on 21 December 2006 that GRSE awarded France's DCNS a contract to provide a comprehensive engineering package of raft mounted Propulsion Power Transmission Systems (PPTS) for the four corvettes. Under the contract, DCNS will deliver four propulsion packages (consisting of eight reduction gear units on cradles and either thrust blocks) to GRSE. The company will also provide support to GRSE for the mechanical integration of the propulsion plant. DCNS is partnering with Walchandnagar Industries Limited, to provide the raft mounts and other components, including thrust blocks and systems auxiliaries. The first propulsion package was delivered in 2008, with the remaining three to follow at the rate of one per year till 2011.

Armament is to include a license-built Otobreda 76 mm Super Rapid gun in a stealth mount and the usual assortment of weapons similar to what is found on the Talwar class frigates and Shivalik class frigates including a Klub-N missile system in vertical launchers, two Larsen & Toubro built derivatives of the RBU-6000 anti-submarine rocket launcher, as well as Larsen & Toubro torpedo launchers. Revati, the naval variant of the DRDO-made Central Acquisition Radar (CAR), is a confirmed sensor aboard the vessel. Hangar and aviation facilities will also be standard features.

Gawron Class Corvette

The Gawron class or Projekt 621 is a class of multipurpose corvettes ordered by Polish Navy. The Gawron class is a variant of the MEKO A-100 project developed by the Blohm + Voss shipyard in Germany. Construction of the first ship of the class started in 2001.

There were plans to build 7 Gawron-class corvettes, but as of 2009, work has only begun on one ship, which is to be named Ślązak. The program suffered delays due to insufficient funding from the government and delays in choosing final weapons and systems configuration. The hull was launched on 16 September 2009, but the program was suspended due to the ongoing financial crisis. Work has now resumed and the first ship should be commissioned by 2015.
