1. C295 AEW&C
Airborne Early Warning and Control (AEW&C) aircraft are high value air assets in modern armed forces and homeland security departments, as they enable the air forces which use them to have superiority over other forces deploying aircraft in a specific air space. Airborne Early Warning and Control (AEW&C) is based on an airborne radar system installed on an aircraft, the main mission of which is to detect far off air targets. Even more so, it denies the enemy the use of that specific air space.
AEW&C is critical because it provides decision makers and commanders with key early warning intelligence, allowing them to make prompt decisions that will ensure their air superiority, in case of conflict.
The AEW&C system is already used for homeland security missions, providing air surveillance of low flying airplanes involved in illicit activities such as smuggling , drug trafficking or insertion of goods and personnel related to terrorism. Furthermore, the organization of mass events often requires the use of AEW&C systems for protecting against eventual terrorist threats.
Airbus Military has signed an agreement with IAI/ELTA in June 2011 at the Le Bourget Airshow, according to which IAI/ELTA will provide the primary sensor for the AEW&C, the 4th Generation Active Electronically Scanned Array (AESA) Radar with integrated IFF. This radar will be fitted into a six metre / 19 ft 18 in diameter rotodome mounted onto the C295.
Both rugged and versatile, the C295 provides a new and very cost effective platform for the so far uncovered medium size market for AEW&C solutions. The C295 AEW&C has been conceived to provide high quality 360º surveillance, creating in real-time an integrated Air and Maritime Situation Picture and Electronic Order of Battle. The AEW&C Situation Picture is shared with friendly forces via Network Centric data links.
ELTA Systems and Airbus Military are now conducting engineering studies to integrate the mission suite, including AESA radar, among other sensors, with the FITS into the aircraft.

2. India's EMB-145i AEW&C aircraft
"We wanted our user to get the best. We had to be customer-driven from the word go," says Dr. K. Rajalakshmi, project director of the DRDO's AEW&C project, which, as Livefist reported last week, gets operational this year.
Categorised as a sensitive project given the classified nature of the sensors, electronics and systems on board, Livefist was given rare up-close access to the EMB-145i after it flew a test sortie at Aero India today, and a chance to interview the highly motivated team driving the project to delivery.
To the global market, DRDO and the MoD offer the EMB-145i in three possible categories: (a) A total solution, available as is (with modified tactical systems according to user needs), (b) As a sensor package adaptable on user-identified platforms, and (c) as a modified version of the EMB-145i that involves a co-development/component model.
"The big advantage is cost-effectiveness," says Dr Rajalakshmi. "No comparable system has all of the features that the EMB-145i has, and it's the only aircraft in its class with an in-flight refuelling capability."
"The sensors and systems are fully Indian, and this is a big advantage for the end user. We want the IAF to get the best," says Dr M. Easwaran, Associate Director at CABS, and designated project director on the proposed AWACS programme.

3. Hercules EC-130V
The EC-130V Multi-Mission Aircraft combined a C-130H airframe with the APS-125 Radar and Mission System of the US Navy Hawkeye. This aircraft was for counter-narcotics missions requiring greater endurance than the E-2 could provide, but was also evaluated for Search and Rescue, Fisheries Patrols, EEZ enforcement and as a support aircraft for NASA Space Shuttle launches. Externally the EC-130 differs from a standard Coast Guard C-130 with the fitting of a large rotodome housing the APS-125 radar. Internally the mission system is palletized and was rolled into the C-130 cargo bay to complete the conversion..
Due to budget cuts in the Coast Guard, the EC-130V program was terminated. This aircraft was transferred to the USAF in 1993 as the NC-130H for further development including upgrading to the latest APS-145 Radar.
The C-130J-30 AEW&C is based on the stretched variant of the Lockheed C-130J Hercules II, which features a new engine and propeller combination and digital flight station for two pilots. The C-130J-30 AEW&C is fitted with the AN/APS-145 on pylons above the rear fuselage of the aircraft. A tactical command centre and crew rest module is fitted into the cargo compartment to contain seven operator consoles and the Northrop Grumman (ESID) Group II+ mission system derived from the E-2C Hawkeye. Lockheed Martin have teamed with Northrop Grumman (ESID) and Transfield Defence Systems of Australia for the C-130J AEW&C.

This is combined with a Boeing designed Open Systems Architecture (OSA) mission system with six common console stations for the mission crew. The OSA mission system is Standards based and uses 80% Commercial Off The Shelf (COTS) software.
A Multi-role Electronically Scanned Array (MESA) radar is the critical sensor aboard the 737 AEW&C. The MESA radar is the latest generation airborne surveillance radar system for mid-cost AEW&C. The electronically scanned array features three apertures sharing "L" band frequency transmit and receive modules to attain 360 degrees of coverage. The "L" band frequency is an optimum blend of range, detection capability, size and weight. The steerable beam, L-band electronically scanned array is designed to provide optimal performance in range, tracking, accuracy and growth. The radar is able to track air and sea targets simultaneously and can help the operator maintain control of high-performance aircraft while continuously scanning the operational area. The 'top hat' provides a practical solution for fore and aft coverage while maintaining the low drag profile of the dorsal array system. This allows the system to be installed on the mid-size 737-700 platform without significant impact on aircraft performance.
The 737 is one of the most popular and reliable jet aircraft in the world. Airlines and operators have ordered more than 4,800 737s, with more than 3,800 having been delivered. With so many in service, there is a world-wide base of suppliers, parts and support equipment.

"The Erieye radar has an instrumental range of 450km and detection range of 350km."
The laser warning system is based on the Saab Avitronics LWS-310 laser warner operating in the 0.5 to 17 microns wavelength bands. Spatial and spectral coverage is provided by an array of three sensors on each side of the aircraft.
The missile launch and approach warner (MAW) is based on the Saab Avitronics MAW-300, which can simultaneously monitor and track up to eight threats. It has four sensors, two on each side, and each with 110° azimuthal coverage to provide the overlapped 360° spatial coverage.
The BOL dispenser is a high-capacity, 160-cartridges, electro-mechanical chaff dispenser. The BOL dispensers are installed in the fairings under the wingtip-mounted radar warning pods. The dispenser incorporates vortex generators which provide chaff blooming characteristics and a chaff cloud Doppler response.
The aircraft is fitted with two Rolls-Royce AE 2100A turboprop engines developing 3,095kW. AE 2100A is a two shaft gas turbine engine equipped with a 14-stage high pressure (HP) compressor driven by a two-stage HP turbine. The engine also features a planetary reduction gearbox connected to the propeller. It also features a full authority digital engine control (FADEC) to manage both engine and propeller.
The length and diameter of the engine are 11.8in (0.29m) and 19in (0.48m) respectively.
