The EA-95 Maritime Patrol Aircraft is designed to answer long stadning requiremnts by the Elias Navy to have organic patrol capability and eventually teh task of maritime surveillance will be transfered completely from the Air Force. Although they have provided capable and dependable service for the past 40 years, teh Air Force's fleet of Il-38 and Tu-142 Maritime survelliance aircraft are approaching the end of their fatigue life. Faced with the first airframe retirements as early as next year, the Elias Navy required a whole system approach to preserve maritime armed surveillance intelligence and reconnaissance capabilities. That whole system is the EA-95 'Cormorant' Multimission Maritime Aircraft.


Design

The Elias Aerospace Corporation was faced with a challenge when the Navy's procurement board specified an amphibious design but once again EA met the challenges and prodcued a superb design. The design of the aircraft focuses around large swept wings with a moderate aspect ratio and a high lift vconfiguration. The fueselage of teh 'Cormorant' uses a variable rise bottom, providing considerable improvements in stability, controlability as well as reducing the power and speeds needed to take off from water. The EA-95 can takeoff in swells of up to 8ft and its high mounted engines are protected from spray and therefore salt corrosion. Effeiceincy and therefore range is further imrpoved by using a pair of High Bypass turbofans produced by Elias Precision Engineering and they have proven in tests to be ultra reliable in nearly all enviromental conditions and in conjuction with integrated fuel control systems offer very good fuel economy and performance.

The fuesleage of the 'Cormorant' includes an internal weapons bay and a large cargo door on the port side. When not being used for maritme patrol or ASW wmissions the EA-95 can be used to move cargo and equipment. The main fueselage can accomodate up to 75 personnel if nedded or up to 52 casualty litters. Normally the EA-95 has two Rigid Inflatables that can be deployed through the cargo door for a range of tasks.

The EA-95 includes an noise mounted air to air refuelling probe as standard.

Sensors and Crew Stations

The cockpit is configured for two-pilot operation. The all-glass cockpit features many of the systems, displays and architecture found in modern airliners with several changes. The flight deck has seven full colour liquid crystal displays for mission information, flight navigation and FADEC displas which eliminate the need for a flight engineer.

For the role of maritime surveillance and anti-submarine/surface operations, the aircraft normally carries eight crew - the tactical co-ordinator (TACCO), the Deputy TACCO, two radar and electronic support measures officers, two acoustic sensor officers as well as twp flightcrew. For longer missions a relief crew can be accomodated.

The tactical crew has identical workstations each with two full colour, multi-purpose displays. The Deputy TACCO manages the communications, navigation and electro-optical systems. The TACCO receives the inputs from all sensor operations and, using the tactical aids suite, evaluates the situation and determines the actions to be taken.

For long range surveillance, the 'Cormorant' incorporates an advanced Electrnoically Scanned Array Radar, the ERSS-5600 has surface search modes as well as an air to air mode and is able to track while scan. The radar can detect ship size objects at approximately 300nm and periscope size objects ou to 150nm.

For deployment of sonarbuoys, the EA-95 includes the ERS/EM-1134S Sonarbuoy dispenser which internally stores up to 58 sonarbouys/marine markers/noise makers, using cartridge actuating devices to dispense. Teh Crookfur developed MK9505 Sonarbuoy handling system combines receiver, data interpretation with 128 channel processing and data transmission and display for over 100 sonarbouys.

The aircraft is equipped with a forward looking infra-red (FLIR) sensor installed in a pod within the nose. The FLIR carries out search, detection, identification and tracking of targets and has a detection range of up to 70nm. Two camera systems provide vertical and oblique photography. A magnetic anomaly detector (MAD), for the detection and location of submarines, is installed in the tail section of the fuselage.


Weapons

The EA-95 is equipped with a stores management system which carries out inventory tracking and control, air-to-air and air-to-sea weapon control, and built-in test and fault diagnostics.

The aircraft has a weapons bay with side opening doors at the bottom of the fuselage which can carry fuel tanks, torpedoes and anti-ship missiles in up to six lateral rows. Each wing has three hardpoints, providing weapons pylons for the carriage of anti-ship missiles or air-to-air missiles for self-defence.

Countermeasures

The defensive avionics suite provides jamming against early warning radars and the fire control radars of missiles and anti-air guns. The processing algorithms are installed on a digital computer. The system also incorporates jamming transmitters, phased array antennas and a tail warning pulse Doppler radar, which gives rear-facing hemispherical coverage. The system's deployable countermeasures include dispensers for expendable decoys including chaff and flares. .

For defensive patrols, operated from the new, yet to be released OMP offshore base, Al-Sabir would like to procure six (6) EA-95 "Cormorants". If the new aircraft proves to have satisfactory capabilities, the ASN will procure more and will completely take over all maritime patrol tasks, currently assigned to the ASAF. The total of $672,000,000 will be wired upon confitmation.
