A class in stealth - the world’s best navy corvettes

Vysby is really a large FAC, or at best a light corvette (displacement 640 tons). So is Buyan project 21630.


Hello Sir.As you seem very knowledgeable on such things can I ask you if you have details on the enlarged Visby version ? And if you do,pls share it with us.Would it carry AA missile,how many,which type ? Price range of the vessel ?

I find it peculiar that Visby is so exposed to Air threats but i've heard of a proposed larger,1500 tons version coming soon.

@Mighty Caty you're welcome to add some info if you have it to.

Will it be good force multiplier for PN if some how they can get 12 of these?? and what role they can play effectively against IN??
 
There is no such thing as Milgem-class correct name for that corvette type is "Ada-Class" , Milgem is name of the project aims to home-build three naval vessels : First is Ada-class ASW corvette (the ship people always call as Milgem-class) then TF100-class Multirole frigate and finally TF2000-class AAW frigate.
Why ADA class when the first ship is called Heybeliada?

Its based on the Princess Islands in Istanbul. As for the namesake of the first ship. One of the two main facilities of Turkish Naval Academy for officer training is located in Heybeliada with nearly covering the half of the island. I was there :)

And the best stealth corvette of the world is here:

Kamorta Class indigenous Anti-submarine Warfare (ASW) corvettes are being built by Garden Reach Ship Builders and Engineers (GRSE), for the Indian Navy. Four of the corvettes constructed under Project 28 (P-28) are scheduled to enter service by 2016. The Kamorta Class succeeds the Kora-Class guided-missile corvettes that are in service with the Indian Navy.

The Kamorta Class corvettes will serve as the frontline warships for the Indian Navy. Primary task of the Kamorta Class will be ASW, while the vessels will also be deployed in anti-surface warfare (AsuW) and anti-air warfare (AAW).
The Indian Navy placed an order for the construction of four indigenous corvettes in 2003. The keel for the lead corvette in class, INS Kamorta, was laid down in November 2006. It was launched in April 2010 and scheduled to be commissioned into the Indian Navy in 2014. Kamorta experienced engine and steering gear malfunction during trails in October 2013.

The second vessel, INS Kadmatt, was laid in September 2007 and launched in October 2011. The keel for INS Kiltan was laid down in August 2010 and the ship was launched in March 2013. The last ship in class, INS Kavaratti, was laid in January 2012.

Project 25A Kora Class Guided Missile Corvettes, India
Project 25A Kora Class guided missile corvettes were built by Garden Reach Shipbuilders and Engineers for the Indian Navy.

Design features of Kamorta Class
The Kamorta Class features high tensile indigenous steel hull incorporating a superstructure made of indigenous DMR 249A steel and Carbon Fibre Reinforced Plastic (CFRP) materials. The hull and superstructure are designed to achieve low radar cross section.

The stealthier hull form is designed to deliver excellent sea keeping and manoeuvrability characteristics while also ensuring lower noise and vibration levels. The ASW corvette includes indigenous content of about 90%.
The corvette has an overall length of 109.1m and breadth of 12.8m. The standard displacement of the vessel is 2,500t. The ship complements a crew of 123 including 17 officers and 106 sailors.

Naval gun systems
The OTO Melara 76mm Super Rapid Gun Mount (SRGM) on the bow deck will deliver a rate of fire of 120 rounds per minute. The gun can fire standard ammunition for a maximum range of 16km.
Two AK 630 CIWs (Close-In Weapon Systems), each mounted on either side of the deck, provide close-point defence against anti-ship missiles, precision guided weapons, low flying fixed or rotary wing aircraft and small craft.

Missiles, ASW rockets and torpedoes
The Kamorta Class is installed with a 16-cell vertical launching system (VLS) for firing Barak Surface-to-Air Missiles (SAMs). The Barak SAM system can strike anti-ship missiles, fixed and rotary-wing aircraft as well as UAVs.
The RBU-6000 (IRL) anti-submarine rocket launchers and triple torpedo tubes mounted on the vessels ensure the engagement of enemy submarines.

Sensors and countermeasures
The Kamorta Class integrates Revati 3D surveillance radar, fire control radars and HUMSA (Hull Mounted Sonar Advanced).
The countermeasures against various incoming missiles are provided by Kavach navaldecoysystem. The Electronic Warfare System (EWS) fitted on the vessel further enhances the survivability.
"The countermeasures against various incoming missiles are provided by Kavach naval decoy system."

Helicopter landing facilities
The stern landing deck can support the operation of a single helicopter. The Kamorta Class corvettes are the first Indian Navy ships to be equipped with rail-less helo traversing system and foldable hangar door.

Propulsion
The Kamorta Class is powered by a combined diesel and diesel (CODAD) propulsion system integrating four 3,888kW main diesel engines, two controllable pitch propellers and noise-suppressing raft-mounted gearbox.
The shipboard power is provided by four diesel generators supplied by Wartsila. The Kirloskar Engines, the licensee of SEMT PIELSTICK of France, delivers the engines, while raft-mounted gearboxes are supplied by DCNS.
The propulsion system provides a maximum speed of 25kt and range of about 3,450nmi at 18kt speed.
 
Says who? By what objective standard?
Let's not forget the likes of Saar 5 and Visby?
Lets look at wiki...

Visby: Displacement: 640 tonnes Length: 72.7 m (239 ft) Beam: 10.4 m (34 ft) Draught: 2.4 m (7.9 ft)
Milgem: Displacement: 2,400 tonnes Length: 99.56 m Beam: 14.40 m Draft: 3.90 m
SA'AR: Displacement: 1,065 tonnes Length: 85.64 m (280.97 ft) Beam: 11.88 m (38.98 ft) Draft: 3.45 m (11.32 ft)

Visby - Milgem- SAAR
Speed: 35 knots - 30 knots - 33 knots
Range: 4600 km- 6480 km- 6500 km
Complement: 43 - 106 - 74

For Radars, EW,Weapons and others look at the wiki ( datas are so big and I cant put any link to page because of I m a new member )

Visby:
Milgem:

The Swedes could barely afford 5.

Unit cost in 2004 £100m ($184m)
BBC NEWS | Technology | Stealth ships steam ahead

If you want to compare the value of a £100.00 Project in 2004 there are two choices. In 2014 the relative:
historic opportunity cost of that project is £126.40
economic cost of that project is £142.70

Remember that PN paid the Chinese 175 million dollar each for the four F22, including 6 helicopters

For 12 Visby, assuming the Swedes would sell, expect to pay around 2.35-2.65 billion dollar. Without nothing extra such as heli's, spares, ordbance, training, maintenance etc included in the deal.
