WASHINGTON -(Dow Jones)- U.S. forces in Iraq and Afghanistan are awaiting new helicopters with potentially life-saving improvements, as the U.S. Army prepares to upgrade its fleet of aging CH-47 Chinooks and UH-60 Black Hawks.

The two aircraft are Army workhorses, but current operations have pushed them to their limits. High altitudes and hot weather strain helicopter performance, as does the constant threat of attack.

Boeing Co. (BA) makes the Chinook, including its new CH-47F incarnation. United Technologies Corp.'s (UTX) Sikorsky Aircraft Corp. unit makes the Black Hawk; the new model is called the UH-60M.

The new aircraft will have more powerful engines and better cockpit communications than their predecessors, the Army said. They also have more built-in defensive technology, like flares and suppressed heat signatures, to deflect attack. Older models don't have such survivability features, in part because of the Army's past decisions to cut funding for helicopter countermeasures. Now the service is trying to make up lost ground.

"The CH-47F and UH-60M bring to Army aviation to capability to conduct combat missions and humanitarian assistance in the most extreme environments of our globe," the Army said in response to a Dow Jones query.

The new Chinooks are slated to reach troops in July. They join a 101st Airborne Division air assault unit, scheduled to head overseas in 2008. The new Black Hawks are due to reach troops in early 2008, the Army said.

Both programs are big investments. According to the most recent Defense Department report on weapons costs, the Army plans to spend $23.8 billion for more than 1,000 Black Hawk upgrades, and $13.4 billion for 512 CH-47F Chinooks.

More engine power and new electronic warfare suites will help the new helicopters stay out of harm's way, said Teal Group aircraft analyst Richard Aboulafia. Even so, a helicopter's flight flexibility comes at a cost.

"Every little bit helps. But when people are shooting at you and you're in a machine that does 150 knots if it's lucky, and if it's transporting stuff, it's going to be big and vulnerable. That's basically risky," Aboulafia said.

The new Chinook is due to reach initial operating capability soon, perhaps by the end of June. This is a big step as the new aircraft prepares for combat.

Boeing said the new Chinooks will be much easier to maintain than their predecessors. Also, the company is ground testing a new infrared suppressor, intended to protect the helicopters from some types of ground fire. Meanwhile, new avionics will make the aircraft easier to fly, even in severe dust storms, said Boeing program manager Ken Eland.

"You can move in one-foot increments in any of the six directions you want," Eland said in a telephone interview, describing the performance improvements.

The new Black Hawks will include a common missile warning system to protect against ground threats, as well as a laser warning system to detect laser-guided attacks, Sikorsky said. The new aircraft will have more powerful engines and various improvements to improve reliability, the company said.

"The UH-60M will provide reduced pilot workload, increased lift, better protection and enhanced survivability. It is ideally suited for its mission and provides a safer, more responsive, deployable, versatile and effective weapon system for the Army," said Bob Mastronardi, Sikorsky's vice president of Army programs.

Aircraft, besides the digital / glass cockpit (which will take some time to get used to) is basically like the new VW Bug compared to the old...

Looks teh same outside, but it ain't the same inside...

And if you ever thought that you'd be in a situation where you lacked power, the T700-GE-701D model engines put out 2000 shp per engine.....

As a comparison, the T700-GE-700 engines in an "A" model Blackhawk put out 1380 SHP per engine...

You can almost do everything you could with one engine on a "M" model that you could do with two engines on a "A" model...

They are sweet aircraft.

The claims about ease of maintenance? Well, that has yet to be proven...They're still big aircraft, slinging big weights, and they are going to wear pieces and parts out a lot faster than a light aircraft.

Can't wait to get in one (but it will be a few years for the National Guard)

Check out this video of a Chinook performing at an airshow. I didn't know they could go vertical like that. Impressive.

Spencer,

EFIS is great! No more scanning all the panel for infomation...it's all right in front of you. It makes those "200 and 1/2 approaches" much easier. I think it's harder going back to round instruments after flying in a glass cockpit.

On second thought, we're rotorheads so "200&1/2" approaches are few and far between so just keep it "clear of clouds" and look at the pretty colors on your EADI.:wave: Well, maybe not with your NVG... ARMY flying:wacko:

MOHAWKS(OV-1D)FOREVER!:D

There are very few helicopters that have the power to weight ratio of an empty Chinook - it'll outclimb most, and it's a lot more maneuverable than most folks think (it was always fun when we had a pilot new to Chinooks that came from Huey's or Kiowas, they were usually stunned) :)

Seems like I recall about 3500 fpm when light, if you started from high speed & did a cyclic climb & added a bunch of power you'd see over 5k for a while...

The most interesting chinook is the USAF's HH-47. They will be used for long range CSAR operations, reportedly. It has inflight refuelling capabilities and I'm sure an aray of night ops. and accurate navigation equipment. I feel this is the first steps to replacing the aging H-53's in their spec. ops. squadrons. Who knows, after all the government may have us driving pedal-powered machines in the future.

When I visit family near Fort Campbell I see a few SOAR MH-47's out trainning in the evenings...COOL!

Speaking as an army vet and someone who studied russian equipment, I think the helis need to have a lot more armor. Flares and heat signature reduction is nice, but bullets, RPGs and anti-tank weapons are more of a threat than heat seekers are.

Just as an example, the chechens used to use three shooters to penetrate the cockpit by using the same aimpoint and firing (close to) simultaneously. Bolt actions were preferred or the SVD, because the AK didn't have enough accuracy or punch from a distance.

The Hooks will lay down some bigs knots in a hurry, too! Snake pilots used to get ticked about getting passed by a Hook. We had to punch off a heavy sling that was misrigged once. It would have been nice if my pilot would have given me a three-count to find a seat. Talk about vertical! Planted my butt on the deck real fast. I was just glad I wasn't on the ramp.

We had a different name for them in Viet Nam.

We affectionately called them $hithooks because you could hook all kinds of $hit to them and haul it anywhere.

I witnessed a Huey UH1 getting shot up by a 51 cal.
The Huey barely made it back to LZ Professional.
A couple of days later a $hithook was sent to fetch it back for repair.

The beast never strained under the load.

Yeah, we used to have to slow down if being escorted by Cobras - they couldn't keep up :)

We could also carry Hueys as a slingload about as fast as they could fly on their own...

I was luck enough to at Ft rucker when the XCH-62 airframe was hauled up from Mobile under a Hook. It was weird seeing a Hook carrying a helicopter larger than itself. I hear the 62 was demolished. Not that it mattered, it never had engines, or pretty much anything else, ever installed.
