Yep - I-Class. It's also heavier at 3,000 tons.
I believe Turkey will allow Pakistan to modified at least 2 vessels to house bigger tubes to launch ground attack cruise missile Babur.

Heybeliada, lead ship of the Ada class corvettes
The MILGEM project, from the Turkish words Milli Gemi (National Ship), is a Turkish national warship program with the aim to design and build locally a fleet of hi-tech stealth multipurpose corvettes and frigates that will replace older ships which are currently in service. Through this ambitious program, Turkey seeks to improve national military shipbuilding capacity and skills and ultimately to achieve independence from foreign weapon producers, designers and manufacturers. More than 50 local companies, including the largest Turkish defense firms such as Aselsan, Havelsan and RMK Marine, play a significant role in the MILGEM project, gaining invaluable experience in warship design and construction. The MILGEM Project Office of the Istanbul Naval Shipyard Command executes and coordinates the design, development and construction works of the MILGEM project since March 12, 2004. The programme initially included the construction of 12 ships in two batches (blocks, due to important differences among the batches). The first batch would have included eight (8) multipurpose corvettes the so-called MILGEM Block I (Ada; island in Turkish) class while the last four (4) would be of the TF-100 frigates equipped with vertical-launching system (VLS) for surface-to-air (SAM) missiles. This plan changed recently as the first batch will include only four corvettes of the Ada class, while all the rest ships will be designated as MILGEM Block II.

In 2014, the head of naval projects for SSM, said that a request for proposals (RfP) for the Batch II (from ship 5) corvettes (also known as MILGEM -G) was expected to be issued by the end of the year. At the same time he said that work on the previously planned TF-100 project for a light frigate to replace some of Turkey's older MEKO 200 frigates had been stopped as "this role will now be covered by the Batch II MILGEM ". The new ships will have an increased length of about 10m and they will include in their equipment a) an Mk41 VLS for Evolved Sea Sparrow Missiles (ESSM), b) Phalanx CIWS instead of RAM (logically from the decommissioned Gabya-class frigates), c) two more quadruple SSM launchers, d) perhaps 25mm RWS/guns such as STOP (instead of STAMP), e) further combat system upgrades, f) new anti-torpedo system and g) diesel engines. The ships of the MILGEM Block I will replace gradually the six D'Estienne d'Orves-class/Burak class corvettes while the MILGEM Block II will replace the non-modernized Gabya/O. H. Perry class frigates (4 in service) and the Yavuz (MEKO 200TN Track I) class frigates (4 in service). This year the designation name of the new Batch changed to I-class.

Till today (June, 2015) only two corvettes have been commissioned by the Turkish Navy and two more are in different phases of construction. The lead ship of the class, TCG Heybeliada (F-511) was launched at t the TNFC's Istanbul Naval Shipyard on September 27, 2008. The cost of the lead ship was around US$260 million. The ship entered in service on September 27, 2011. On the same day and at the same shipyard, the TCG Büyükada (F-512) was launched and exactly two years later, in 2013, she was commissioned into Turkish Navy. The same day the keel for the third ship TCG Burgazada (F-513) was laid. However, the MILGEM programme encountered major setbacks in 2013 that cast doubt over the project's future. Under the original planning a nominated private Turkish shipyard was to work together with Istanbul Naval Shipyard on the third and fourth ships in Pendik in order to transfer the know-how required for the construction of subsequent ships in its own facility, and RMK Marine was selected in January 2013. However, contract negotiations were halted in mid-2013 when a complaint from SEDEF Shipyard sparked a probe. In August the prime minister's inspection office concluded that the tender for follow-on ships was not held in a competitive manner and should therefore be cancelled. The SSM's (Turkish Undersecretariat for Defence Industries) executive committee acknowledged the findings of the inspection office inquiry during a 26 September 2013 meeting and set out a revised procurement strategy in which it was decided that the fourth corvette would now also be built at Istanbul Naval Shipyard while a new tender was opened for the I-class ships. The experience and technological know-how gained with the MILGEM project will play an important role in determining the design characteristics and the development process of the anti-aircraft warfare TF-2000 class frigates.

The general characteristics of the class is a displacement of approximately 2,300tons at full load, length of 99.5m, beam of 14.4m, maximum speed of +29 knots and a range of 3,500n.m. with the cruising speed of 15 knots. The crew is only 93 people while there is accommodation for 106 passengers including flying crew and technicians (11 people). The propulsion is combined diesel and gas (CODAG) propulsion system, which consists of a gas-turbine and two diesel engines delivering a power of around 30,000kW. The ships carry one medium helicopter (S-70 Seahawk) which can be accommodated in a hangar. Additionally, each corvette carries two rigid-hulled inflatable boats (RHIB). The ships feature a steel hull and fragmentation resistant composite superstructure. Fore and aft masts and the funnel have been constructed with sea resistant aluminum alloys. The warships of the MILGEM project are designed to fully operate at sea state 5 and partially operate at sea state 6. Reduction and management of the ship signatures was taken as the major input during the whole design phase. Many classified precautions were taken in order to reduce hydrodynamic, acoustic, magnetic signature, Infrared Signature (IR), Radar Cross Section (RCS), and therefore, to achieve the specified level of stealth feature. Collective Protection Zones are designed to ensure the ships ability under NBC conditions. Locally designed degaussing system minimizes the magnetic signature for protection against the magnetic mines. The design focused on reduced Life Cycle Cost while the configuration is easily adaptable to technological improvements and changes due to operational requirements.

The 76mm gun in action!
OTO Melara Super Rapido gun system
Each ship of the class is equipped with a fully automatic
OTO Melara Super Rapido main gun of 76mm/62cal fitted with a stealth cupola and located on the bow deck. The gun is capable to intercept air and surface targets at a distance of 16 km (the effective range is between 5 and 8km) unleashing 120 rounds per minute weighting greater than 6 kg each. In comparison with the basic Compatto of the same manufacturer Super Rapido has an increased rate of 35 rounds per minute. The revolver magazine in the mount holds 85 ready rounds. The gun is remotely controlled but there is provision for an emergency local control as well.

Except the main gun, for the purpose of asymmetric warfare and coastal defense, the corvettes are equipped with two
Aselsan Stabilized Machine Gun Platforms (STAMP) with 12.7mm heavy machine guns. STAMP incorporate advanced features, such as remote operation, built-in electro-optic sensor system, day and night operation, automatic target tracking (detect, track and fire on the move) stabilized turret and ballistic computation. The infrared and daylight TV cameras of the system enable detection and recognition of targets that would not be possible with naked eye. The system is capable of ballistic calculation and automatically tracking the targets and enabling a high hit probability by accurate firings. STAMP System has a stabilized turret which enables the line-of-sight of the gun to be aimed at the target at all times. Due to the stabilization feature, the system can perform precise firings against stationary or moving targets while the platform is on-the-move. System can be operated remotely by using the remote gun control unit and hence provides gunner protection against counter fire. System has additional features of defining firing zones both in azimuth and elevation.

For specialized anti-aircraft and anti-missile defense (CIWS), the vessels of the class have one Mk 49 Guided Missile Launching System (GMLS) with 21 missiles each ready to launch
RIM-116 Rolling Airframe Missile (RAM) (Block 1A). The launching system is located atop the helicopter hangar. Together, missiles and launching system comprise the RAM Mk 31 Guided Missile Weapon System (GMWS). RAM is a class-leading weapon system providing a full perimeter protection to the vessel operator. The Block 1A missile has infrared guidance system that enables it to intercept missiles that are not emitting any radar signals while the Block 0 passive radar homing capabilities have been retained. The range exceeds the 9 km and the speed surpasses the 2 Mach.
