Really ? I didn't know that. Thanks for the info.

At a trade show, a Kongsberg guy told me the "body" may be the same original one, but the insides of the missile have been constantly changed as technology improved over the years.

Well, I may have to retract my statement about the amount of damage.

The older models of the AGM-65 that I was familiar with only carried 125 lb warheads. I now see that the newer models in fact carry a warhead of almost 300 lbs.

So, let's look at the most effective versions of each.

Here's the Penguin, AGM-119

Length: 10' 5"
Diamter: 11"
Total weight: 848 lbs
Warhead Weight: 290 lbs
Speed: 740 MPH
Range: 40 miles

...and here's the Maverick, AGM-65:

Length: 8' 2"
Diamter: 12"
Total weight: 660 lbs
Warhead Weight: 300 lbs
Speed: 714 MPH
Range: 12 miles

So, if you consider the warheads and their design (both are similar in size and in fusing) both are going to do about as much damage as the other when considering the warhead alone.

Now, the Penguine is quite a bit longer (which measn it can carry more fuel and get a longer range) and has more structual weight to it. So, that extra weight and mass are going to impart more force to the hit, which means a Penguine hit may infact do more overall damage. But, the vast majority of the damage, particularly to the structure of the ship, with be related to the warhead, and those are about equal IMHO.

As stated, the Penguine does have about 3 times the range of the Maverick, and that is critical to consider.

But if a Maverick can get close enough and be fired and hits a ship, I believe now that it will probably do about as much damage as a Penguine.

Man, I think the sea sprites are NZs only real guided air to ground munition capable aircraft.

Of course, our geography makes anything more than that unnecessary, and the budget won't even support the idea of acquiring fast jets, but it is a bit depressing when the top displays at RNZAF air shows are RAAF hornets...

Wow!

Sounds almost like a helicopter borne version of their Joint Strike Missile.


Main Features:

• State-of-the-art, all digital, fifth generation fire re-and-forget anti-ship strike missile
• Numerous selectable flight profiles and horizontal trajectories
• Stand-off range from outside opponent’s area air defense systems
• Accurate passive midcourse guidance
• Passive state-of-the-art infrared seeker
• Autonomous target validation, tracking and homing
• Unaffected by jamming and IR decoys
• Random high-g maneuvers in terminal phase
• Impact point close to waterline for maximum destructing effect in target

Specs, Helicopter Strike Missile:

• Overall length:156 in / 3960 mm
• Airframe diameter:16 in / 406 mm
• Wing span:
• Folded Wing Span: 27.5 in / 698 mm
• Deployed: 53.5 in /1360 mm
• Launch weight: 880 lb / 400 kg
• Warhead weight: 264 lb /120 kg(Equivalent high explosive weight220 lb / 100 kg)
• Guidance: GPS assisted INS
• Programmable Flight Path
• Passive IR homing
• Cruise speed: High subsonic
• Operational range: 130 km

Now that will give helos a true long range ASM capability.

Royal Navy deploys nine Merlin Mk2 helicopters onboard aircraft carrier for ASW exercise

The Royal Navy’s new submarine-hunting helicopters will face their greatest test yet when they head into the Atlantic this June in the biggest exercise of its kind this century. Nine Merlins from RNAS Culdrose in Cornwall will join HMS Illustrious to practise skills which were once the mainstay of the Royal Navy’s aircraft carrier operations at the height of the tensions with the Soviet Union.

The Merlin is a very, very good ASW helicopter. Among the best in the world.

Illustrious does not have long left...I know that the Ocean is alos intended for this role and it is a good role for such vessels, along with their air and amphibious assault capabilities.

EC725 Caracal armed with Exocet anti-ship missile undergoes flight tests in Marignane

A specialized team of Helibras and Airbus Helicopters experts tested a prototype of the EC725 carrying anti-ship missiles installed on either side of the aircraft. The Exocet AM39 missiles will equip eight of the 16 EC725 helicopters belonging to the Brazilian Navy, which are part of the contract for 50 EC725s signed with the Brazilian Ministry of Defense for the three Army corps.

Yes...as I also said on the other thread...this is a significant capability.

Thanks for posting it here too.

Having a relatively long range and very capable anti-ship/anti-surface missile able to be launched by these helos gives them a very credible strike capability. Particularly if these helos can carry two Exocets each.

A force of four of these helos would be a significant threat to any surface action group or task force. Operating off of a carrier, if they can get in range, they become a significant additional capability.
