MF-STAR
The EL/M-2248 MF-STAR is a multifunction active electronically scanned array naval radar system developed by IAI Elta for maritime installation on warships. It is capable of tracking both air and surface targets and providing fire control guidance. MF-STAR is an acronym of Multi-Function Surveillance, Track And Guidance Radar. Design and description The EL/M-2248 MF-STAR is a multifunction solid state Active electronically scanned array radar developed for a new generation of naval platforms. The radar system is made up of 4 active arrays operating in the S-band, each of the 4 arrays is positioned in one direction. The radar employs multi-beam and pulse Doppler techniques as-well-as robust Electronic counter-countermeasures techniques to extract low radar cross-section targets from complex clutter and jamming environments. AESA radars provide a low probability of intercept of emitted signals and help the ships remain stealthy. Weighing only seven tons the system can be insta ...

Kolkata-class Destroyer
The "Kolkata class" ''(Project 15A)'' are a class of stealth guided-missile destroyers constructed for the Indian Navy. The class comprises three ships – ''Kolkata'', ''Kochi'' and ''Chennai'', all of which were built by Mazagon Dock Limited (MDL) in India, and are the largest destroyers to be operated by the Indian Navy. Due to delays in construction and sea trials, the initial commissioning date of the first ship of the class was pushed back from 2010 to 2014. The destroyers are a follow-on of the Project 15 s, but are considerably more capable due to major improvements in the design, the addition of substantial land-attack capabilities, the fitting-out of modern sensors and weapons systems, and the expanded use of net-centric capability such as Cooperative Engagement Capability. Design The ''Kolkata'' class share similar dimensions to the previous ''Delhi'' class, however they have 2,363 modifications which include major upgrades in weaponry, sensors and helicopter sy ...

Active Electronically Scanned Array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased array technology. PESAs can only emit a single beam of radio waves at a single frequency at a time. The PESA must utilize a Butler matri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Sa'ar 6-class corvette is a series of four German-made corvettes ordered for the Israeli Navy in May 2015. Development The ships' design is loosely based on the German , but with engineering changes to accommodate Israeli-built sensors and missiles such as the Barak 8 and the naval Iron Dome system. Elbit Systems has been awarded the contract to design and build the electronic warfare (EW) suites for the ships. All four vessels were constructed in Germany in a joint project by German Naval Yards Holdings and ThyssenKrupp Marine Systems. The first of the class was scheduled to be delivered in 2020. Construction cost was estimated at NIS 1.8 billion Israeli new shekel (NIS) or roughly 430 million Euros ($480 million).

Sa'ar 5-class Corvette
Sa'ar 5 ( he, סַעַר, lit=storm) is a class of Israeli Navy corvettes. They were Israeli designed using lessons learned from the s. Three Sa'ar 5 ships were built by Huntington Ingalls Industries (formerly Litton-Ingalls Shipbuilding Corporation of Pascagoula, Mississippi) for the Israeli Navy, based on Israeli designs. They were the largest surface warships in Israel's naval fleet, although the Sa'ar 6-class corvette now being deployed are considerably larger. Although classified as "corvettes" due to their small size and crew of only 71, their weaponry and speed are almost comparable to that of a frigate. They are equipped with sonar, 2 triple torpedoes, 2 quadruple missile launchers, electronic warfare capabilities and decoys, a Close-in weapon system, 2 autocannon and a helipad and helicopter hangar. The first of class, , was launched in February 1993, followed by in August 1993 and in March 1994. Combat history On 14 July 2006 during the 2006 Lebanon War, INS ''H ...
