The struggling CSAR-X program continues to muddle through its legal challenges and contract re-bidding. Others have covered this story in much greater depth than we have here at Defense Tech, but as issues pop up, well update readers on the latest tid bits.
One such issue emerged today after reading an outstanding feature story in the Washington Post on the rescue of SEAL Petty Officer 1st Class Marcus Luttrell who survived a June 2005 Taliban ambush that wiped out the rest of his team.
Buried deep in the story is this passage:
Planners first considered sending a Chinook to get Luttrell, while Peterson’s HH-60 would wait five miles away to evacuate casualties. But the smaller HH-60, the planners concluded, could navigate the turns approaching Sabray more easily than a lumbering Chinook.
So in one of the highest-profile rescues of the Afghan war, Air Force PJs opted for the smaller, nimbler HH-60 to pluck Luttrell out of a remote village ringed by Taliban guerrillas. Yet the Air Force picked a variant of the twin-rotor Chinook to replace its fleet of HH-60 Pave Hawks.
A few days ago, DT got word of a letter to Sen. John McCain (R-Ariz.) written by a former AFSOC commander wondering why the Army picked the heavy-lift CH-47 to replace the medium-lift Pave Hawk.
It is my understanding that the HH-47 was awarded the contract largely on the basis of its advantage over the US101 and S92 in range and payload. That is to utterly miss the point of combat rescue. First, unrefueled range is a non-issue in the age of helicopter air-to-air refueling.
Second, above and beyond the ability to carry a basic crew, defensive armament, limited armor protection, and a reasonable number of survivorswhich all three contenders can dopayload is not a critical issue for a CSAR helicopter and never has been. The HH-47’s advantage in payload is a direct reflection of its size, and size is a liability not an advantage.
wrote Dr. John F. Guilmartin, Jr., a distinguished Air Force rescue pilot and AFSOC commander.
The HH-47’s liabilities extend beyond size and lack of agility. It has more violent rotor downwash than the other contenders, a reflection of its weight and tandem rotor design. Partly in consequence, it is far more susceptible to brownout (a lethal condition in which pilots lose visual contact with the ground during landing or takeoff due to dust and dirt blown aloft by rotorwash). The combination of violent downwash and interaction between the counter-rotating columns of descending air from its two lifting rotors make it a poor platform for rescue hoist operations, the bread and butter of sea rescue and overland combat aircrew recovery. It has a significantly higher vibration level than the other contenders, a matter of serious concern in terms of crew fatigue. The fields of fire of its defensive armament are significantly more constricted than those of the other contenders. Its aural signature is significantly greater, affording the enemy more warning on low altitude ingress. Lastly, it requires a much larger landing zone than the other contenders, seriously constricting its use in urban areas and from shipboard (the thought of having had to conduct the Saigon evacuation, in which I participated, with H-47s is truly frightening).
Guilmartin added.
Sources tell DT Guilmartin may have something here. Most observers were astonished that the 47 was picked over the Lockheed Martin/Augusta-Westland US101 and the Pratt-Whitney/Sikorsky S-92. But others saw the writing on the wall.
Im not sure what happened with CSAR-X, but the scuttlebutt has it that General Brown and the Army C-47 lobby got to the USAFperhaps a quid pro quo for LCA, for Predator orbits, who knows. But, it was a very, very odd selection and choice. You should see the pictures of C-47 brownout compared to the other two, both of which have specific rotor designs that cause a doughnut of clear ground around the chopper that would actually help a rescue by obscuring the helo and the downed pilot from the enemy if they were close-by.
The C-47 decision seems odd, because somehow the old C-47 mafia (including Brown) somehow got their way at the 11th hour (the C-47 wasnt even a competitor until late, which also has an aroma about it).
Another AFSOC veteran tells DT:
I think the bigger issue is who flies helos? If the Army flies them then we should expect that they will be misused and shot down more often. Simple matter of different cultures, training and what kind of competency the crew has
If we really transform, who needs CSAR. It will be done by UAVs.
And on the UAV issue, our first source adds
UAVs were proposed for CSAR in Vietnam — the Navys drone anti-submarine helicopter (DASH) which flew operationally from destroyers and frigates from about 1964 to 1971. The last of the DASH test articles made its final flight recently. They were great little machines and the Navy grossly mismanaged their operational employment, and they were replaced in the 1970s by LAMPS (now the SH-60 Mark III Seahawk).
Sikorsky and Lockheed Martin continue to fight the Air Force on its choice, blasting the service for its tepid revision of the request for proposals mandated by the Government Accountability Office.
Its unclear when and how this will all shake out. While the momentum seems to favor the Boeing bird, the two competitors arent giving up quite yet.

And why didn’t they send an HH-60 for the evac from Takur Ghar Mountain, which was the highest profile rescue? Perhaps the fact that an HH-60 can’t actually land and take off at that altitude had something to do with it? Unlike an CH-47, which can and did.
It’s possible that there is more to the eye than is seen here. Perhaps there is a mission profile we haven’t seen yet. These C-47 would do very well to insert as well as extract. Plus, it would keep manufacturing base going for cheap parts to extend the life of the current fleet of helos.
C-47? Isn’t that the C-47 Skytrain? I believe the Boeing helicopter in question is officially the HH-47.
The HH-47 will be a great asset for the AF. Of course the ACFT kicks up more dust. It’s bigger! Of course it’s not a nimble. But we’re not flying jets now are we? The capability that the 47 offers compared to other helicopters is second to none. I could go on all day about how the 47 compares to other ACFT. You have to look at the theatre’s we’re operating in, what the AF needs, and the MISSION! The Army already uses it this capability. And it was thought that the HH-47 was to replace the 53. Which has a horrible track record compared to the 47. All in all, I believe it’s about the mission and capability. The 47 has proven time and time again that it can do it all. The AF wants what the Army already has. A great helicopter!!!
Sure, the insurgents will probably upgrade to portable SAMs if RPGs aren’t effective – action/reaction is always the pattern. However, RPGs are cheap, and portable SAMs aren’t. At the very least, forcing the enemy to use SAMs to achieve a kill makes it more expensive for them to operate.
Each branch of the military is unique and different. Each branch has different needs and wants as well as different missions. There is no such thing as one plane, or helicopter for everyone , just will not work. Let each service decide what they want! Yes cost is a major factor but so is waste! The reason we cross train with each other is to learn the capabilities of what each service , their equipment, and what their people can due. Hopefully if it costs so much to oufit everyone for war maybe cooler heads will prevail. The cost to fight a war in the long run will cost more then to fight for peace. P.S. yes unfortunatly wars are neccessary.

IN the trenches we call the CH-47 “Shit HooK” and that’s for a reason. The majority still in service have magnesium infrastructure which burns at 2000F even udner water and nothing is left of it once fuel ignites it. No crew either.
2nd its lift is what it was built for, mil-vans, arty, troops. Tail-gating on jumps are fun too, but it is an egg beater and at high altitudes and in close quarter Ops ask anyu pathfinder which he would rather vector-in. Plus, how many have we lost in 5 years in the GWOT? MAtch that to H-60′s of any service. Sea Kings are even a better choice or Dolphins.
First of all I must qualify my comments or reason for wanting to see the HH-47 as the next generation of CSAR/JCSAR aircraft. I have logged over 14,000 hours of helicopter time and most of that has been in M/Y or CH-47 A, B, C, D & E models Chinooks.
I also have hours in YUH-60 and 61s as well as most of the Hueys and Little Birds series. The other helicopters are of various origins and manufactures.
With that said I must ask those who have
