To further boost its capabilities, the Department of National (DND) announced that modern submarine detection equipment will be fitted in its P5.9-billion long range patrol aircraft (LRPA) acquisition project.
In a supplemental bid bulletin, the DND said two aircraft are expected to be acquired under this program.
Submarine detection equipment which the DND is requiring to be fitted include:
*Magnetic anomaly detector which is capable of detecting minute variations caused by the passing of large ferrous objects such as ships and submarines through the Earth’s magnetic field. It should have ISO 9001:2008 certification;
*Sonobuoy processor which can provide underwater acoustic signal acquisition and processing capabilities that help to quickly and accurately detect, classify, and tract submarines in complex undersea environments. It should also have ISO 9001:2008 certification;
*Sonobuoy receiver which can listen and receive signalscoming from sonobuoy transmitters which have been dropped in the water. It should also have ISO 9001:2008 certification;
*Sonobuoy (Active) which is capable of emitting sound waves into the water and listen for the returning echo before transmitting, usually range and bearing information via UHF/VHF radio to the aircraft.
-Likewise, it should localize targets both range and bearing in extreme environmental conditions against a very quiet submarine or in an attack mode.
-It should allow short and long range detection of surface ships and submarines. It should have a transducer tointroduce acoustic energy into the water and to manipulate the return echoes which are amplified and for VHF radio transmission.
-These are usually designed for deeper depths than passive buoys.
-One hundred pieces of active sonobuoy should be providedby the winning bidder.
*Sonobuoy (Passive) which should emit nothing into the water but rather listen, waiting for mechanically generated sound waves (for instance, power-plant, propeller ordoor- closing and other noises) from ships or submarines to reach the hydrophone that are then transmitted via UHF/VHF radio back to the aircraft. The received signals should be transmitted to any monitoring unit that then process the signal for analysis, classification of any target, and recording on magnetic tape media for replay and post eventanalysis.
DND undersecretary Fernando Manalo, Special Bids and Awards Committee-1 chair, earlier said bid opening and submission is slated for Aug. 11.
It will be held at the bidding awards committee conference room at basement, right wing, DND building,
Money for the long-range patrol aircraft project will be sourced from the Armed Forces of the Philippines (AFP) Modernization Act Trust Fund.
The contract includes sensors, sensor integration, mission support facilities and integrated logistic support, Manalo said.
Winning bidders are required to deliver the aircraft within 1,035 calendar days upon receipt of the notice to proceed.
Manalo added that participants must have completed a similar project within the last 10 years.
