CSAR-X update. HH-47, not the best fit but you get it anyway!

It is not uncommon for companies to be a tad upset when they loose out on a major aircraft contract. It seems in this case that Sikorsky and Lockheed Martin/AgustaWestland (Lockmart/Mangusta from now on) has a good case for complaining. GAO report B-299145.4 It would seem that the HH-47 did not do so well in a few areas. One huge area is the fact that the HH-47 can not land on over 80% of the Navy’s ships. That is a huge concern being that it would be a search and rescue Helicopter and a good portion of the recoveries would be in the ocean. They would loose out on sometimes closer medical help if a ship was out of the question and they had to land back on dry land. Both the EH-101 (damn sorry, US-101) and the H-92 can land on all ships that have a landing pad.

Again, the HH-47 has massive downwash from the twin counter rotating rotors. Of the nine Chinooks lost in Afghanistan, two have been because of the “brown-out” associated with the downwash. This is a huge concern when trying to recover someone on the ground and have to use the hoist to lower a Pararescuman (PJ) to recover the victim. That PJ will not only have to fight the enemy, the elements and sometimes the victim...but now he will have to fight the helicopter as well.

Like POGO has pointed out. The HH-47 almost missed a key area. One of the requirements was to build up the helicopter after an airlift to an “area” in less than 3 hours. The documents point out that Boeing made this mark with only 2 minuets to spare…but, the document had deleted the times by both the Sikorsky and lockmart/mangusta aircraft.
It looks like because of this, the requirements were changed from MR to FR (Mission Ready to Flight Ready) which means that the time is based on just the minimums to get airborne and not to accomplish the mission. This is unacceptable. It looks like both the Sikorsky and Lockmart aircraft can become Mission Ready within two hours.

MH-47E Army'sversion of the HH-47

It is sort of funny that while between 2002-2003 when the CSAR was under the ACC USAF command that the HH-47 was brought up and then dropped from the list early on because it was not acceptable for the mission at hand but once the mission was transferred back to AFSOC and then under USSOCOM that the HH-47 found its way back onto the list. It seems that someone on the Army side of the command has a soft spot for the 1960’s era aircraft.

The GAOs report has deleted almost everything that might have favored both Sikorsky and Lockmart’s aircraft…we can only assume that the HH-47 has failed, and that someone still liked it within USSOCOM and passed it through…or is this a bone for the screwed up KC-767 deal?

IMHO, I still feel that the Sikorsky would be the best fit on just the parts availability alone. The HH-60 it would replace is Sikorsky and its sister the MH-53M is also a Sikorsky product so then, why would you throw the Boeing product in there (while the US ARMY is having parts issues with the MH/CH-47s)

KC-X when will you come, and who will you be?

Our air refueling tanker fleet is older than dirt. The KC-135s have been passing gas for 50 years (first flight August 1956, first delivered June 1957)
Stratotanker
They still do a great job and I am hard pressed to think of another plane that can do as good of a job. Sure there is the KC-10 but that has been sort of a flop. The KC-10A (DC-10)and now with that aircraft gone from the airlines support for the aircraft is a huge issue...not to mention this. Some aircraft have a very hard time refueling under the large KC-10. The C-130s that have the capability to be on the receiving end of the KC-10 have to dive down and more times then not, it takes three or more connections to fuel up...not only is that in efficient, its unsafe. They are more of a cargo plane than a Tanker.

What is on the table? For right now there are two proposals.
One from Boeing and one from Northrop Grumman (Building an French Airbus)
I do not fully agree with Boeing's offering. They want to give us a tanker version of the 767.Photo Sharing and Video Hosting at Photobucket

the 767 is a great aircraft but it is already 25 years old...and if we keep her working as long as the KC-135 then she will be well over 75 years old. C'mon we can do better than that. I understand that a lot of the cost will have been offset because both Japan and Italy are now flying variants of the aircraft. She is already ancient technology. The 777 is too big for the job so I will not even go there. The 787 I think would be a great choice and since she is already in development she would be able to start out much like the old KC-135 did alongside the Boeing 707 (Yes, I understand that they in fact are really different aircraft...but close enough) How would fuel effect the whole composite structure of the 787? I do not know. One thing that Boeing just added to sweeten the deal is the services of Delta TechOps to KC-767 Advanced Tanker Team. These guys (and gals) are top notch in the aviation industry.
Northrop Grumman is trying to pitch the KC-30... (once the KC-330)
http://www.northropgrumman.com/kc30/
this is nothing more than a French built tanker version of the Airbus A330, (MRTT) .
I understand that these too are already flying and will soon be adopted in both the Royal Air Force and the Royal Australian Air Force. I have personal feelings that we do not need to be spending so much money on French aircraft...but, on paper, the KC-30 looks a tad better than the KC-767.

I feel we need a totally NEW design NOW.

In the end I want a US company to win...even if it is the KC-767
