Normally flown by a crew of three, pilot, observer and aircrewman, Merlin was equipped with the Thomson-Marconi active "dunking" sonar, giving enhanced submarine detection ranges, and the GEC Marconi AQS 903 acoustic processor. All crew stations could access the management computers and operate the tactical displays. These were fed by the Marconi Blue Kestrel radar which possesses full 360-degree coverage and an ability to Track-While-Scan surface contacts. It could also pass tactical information via a datalink to other participating units; a significant capability which has not been utilised by maritime helicopters before. Merlin was designed to operate in all weathers from the flight decks of both large and small ships (Invincible class aircraft carriers and Type 23 frigates). It is powered by three Rolls Royce RTM 322 engines, is capable of speeds of up to 150 knots and has a range of 200 nautical miles. It can carry up to four homing torpedoes or depth charges, for use against threat submarines and can provide targeting information via datalink for the prosecution of surface threats. The Merlin retained all the secondary role capability of its predecessor, the Sea King, including loadlifting, casualty evacuation, troop carrying and Search and Rescue. SH(EH101), designated the Merlin HC Mk 3, filled a capability gap between Chinook and Puma. It also replaced the obsolete Wessex. Based on the military utility version of the Anglo-Italian EH101, it was designed to operate by day and night, in hot and high or cold and icing conditions undertaking a wide variety of roles including troop carrying, small vehicle and/or cargo carrying capability. It would support ground forces in a wide range of operational scenarios, including combat search and rescue, in National, NATO and UN operations. A range of role-fit and portable support equipment was also available to further tailor the aircraft for special operations. The Merlin HC Mk 3 was a significant advance on the aged Wessex helicopter and also reflected the progress in both roles and capabilities of support helicopters. The Merlin HC Mk 3 has a single main rotor configuration powered by three uprated Rolls Royce Turbomeca RTM322 engines. It has an all-up take off mass of 14.6 tonnes, maximum speed of 167 knots and range on internal fuel in excess of 1000km. The operating range can be extended by virtue of an air to air refuelling capability and continuous operations are possible. Designed to carry 24 troops in crash-attenuating seating, fitted with active noise reduction (ANR) headphones. The seats can be folded away and a range of cargo or small vehicles loaded via a rear ramp or side door. A cargo winch and roller conveyor for palletised freight are integrated. Under slung loads can be carried. [/quote] this is taken from global security sight if you want to check it out... |

Okay, now I got your contention for the Merlin: 1. Greater range 2. Greater endurance 3. Heavier payload Now, here's mine: 1. Should we have an ASW heli, do the PN needs it to operate at 1k miles radius? If that's the case then it now becomes a land-based ASW platform as per geographical location of Spratly's from Palawan or anywhere from our territory inc Scarborough. 2. Submarines lurking and surveiling warships cannot be at 1k miles away, so no need for Merlin to be ship-based. 3. 200 mile operational radius for Super Lynx is ideal for ship-borne ops as submarines are likely to operate within that vicinity. Plus it's weight cannot be a burden to the frigate should it needs mobility and speed for maneuvering. 4. Super Lynx is cheaper to procure and operate than the Merlin. It is not a matter of carrying capability of the Maestrale or the operational range of an ASW heli. Rather, it's the proficient, efficient and cost-effective conduct of anti-submarine warfare operation as per need and practicality to and for both platforms. In short, the ship and the heli should be synergistic to each other without compromising efficiency. |

Sir, no doubt the Merlin is the "better" ASW platform by virtue of range and endurance. But... The Merlin is too big, too impractical and too expensive for an ASW heli (ship-borne) for the PN. |

a little OT... I think the ship on the background was not a Maestrale class frigate, instead it's a Type 23 (or Duke class) frigate of the Royal navy.

Right. It's a RN Type 23 frigate: If it's F234 then it's the Iron Duke. If F236 it's the Montrose. |
