Mahindra & Mahindra Ltd., one of India’s leading business houses and Telephonics Corporation (Telephonics), a leading designer, developer, and manufacturer of high-technology integrated information, communication and sensor system solutions to military and commercial markets worldwide and a subsidiary of Griffon Corporation (NYSE:GFF), announced today they signed a definitive agreement to form a Joint Venture (JV). The JV will provide the Indian Ministry of Defence and the Indian Civil sector with radar and surveillance systems, Identification Friend or Foe (IFF) devices, and communication systems. In addition, the JV intends to provide systems for Air Traffic Management Services, Homeland Security, and other emerging surveillance requirements.

The Company will be called Mahindra-Telephonics Integrated Systems (Mahindra-Telephonics), and will be incorporated in the coming months following an amendment to the prior approval granted by the Foreign Investment Promotion Bureau on March 31, 2012.

The project envisages establishing a plant in Bangalore, which will initially manufacture and service airborne radar systems that are already being supplied to Hindustan Aeronautics Ltd and support airborne maritime surveillance systems for the Indian Navy and Coast Guard. Telephonics supplies RDR-1400 weather avoidance radar systems for helicopters being built in Bangalore, India. It is also contracted to supply Boeing with APS-143C(V)3 multi-mode Radar for India's P-8i Maritime Surveillance aircraft, and is responsible for installation of a sophisticated intercommunication system for the C-17 Globemaster contracted by the Indian Air Force.

Mahindra-Telephonics will license technology from Telephonics for use on a wide range of products that has both defence and civil applications.

Backed by strong R&D, Telephonics has developed a state-of-the-art IFF MK-XII system, which has the capability to integrate with civil and military aircraft, as well as ground and sea based IFF systems. Telephonics’ experience with respect to these systems in other countries will provide a platform for the JV to meet the emerging Indian customised civil and military requirements of a National IFF Program. Telephonics has also developed secure communication systems which may be deployed on a variety of ground and airborne platforms. Telephonics has an established presence in the Indian defence and civil markets.

The Mobile Surveillance System is a rapidly deployable ground surveillance system which can detect human and vehicular movement during the day, at night, and in adverse weather conditions. Through networking, a central command and control system can effectively monitor a large area for vehicular and human movement.

The JV will be the first private sector company in India to manufacture airborne and maritime radars utilizing licensed technology. Nearly 100% indigenous capability is expected to be achieved in the near future. The JV will also be strategically poised to develop future technologies for civil and military applications.
