Gentlemen,
the a/c indicated by the Majoor is a concept a/c. It is very dangerous to even consider this, although I suspect that it may have been done lighthearted.
A/C are designed from the beginning with specific missions in mind. Hercs are not strategic airlift. They are tactical and the CF has used them to do strategic out of necessity. It is time for the Hercs to be replaced. I agree with the coming decision to replace the SAR Hercs with the Spartan. Do you really need an a/c the size of a Herc to do SAR? No.
I agree that we should maintain a fleet of Hercs, most likely the J model, since we have extensive experience in flying and maintaining them. Thus parts and training would already exist, but would have to be supplemented with upgrading due to the new J model. Extending the fuselage of the Herc will only help with long cargo, not with items that require larger volume, i.e. height restrictions. The E and H models are old and have extensive airframe hours. Lockheed Martin is actually very interested in us since no one else operates older ones. There are certain components that are lifed items, i.e. hours flown, that need to be replaced after certain hours. Just like an engine or tranny in a helo, airframes also reach time limits due to cracks, corrosion, etc.
My understanding is that the Hercs are having their wing boxes replaced at third line at SPAR. This is expensive and time consuming, restricting the availability of the a/c for ops. My recommendation: retire the E's, replace with the Spartan, retire about 10 Hercs immediately, and then phase in the J models for the remaining older Herc models.
Strategic airlift is needed. Look at DART as an example. Look at the LAV or the proposed stryker. I work with Griffons and we have to take the main and tail rotors off, head and mast off, use gross weight tow kit, and then it can barely fit into the Herc. The process of loading a CH146 into a Herc can take the better part of a day. Then it must be unloaded at the destination. With a C17 or Antonov (of which there are dwindling numbers), you can simply fold the blades (using a premium blade fold kit) and roll the helo onto the C17 and then off at the destination. Unfold the blades, do the paperwork, preflight, and you're off. Which one to buy? No brainer, the C17. We have or just had pilots in the States doing trg with them at US units. It is a proven a/c that is built in our backyard. Remember, whenever the Government buys items such as a/c, there must be regional benifits throughout Canada (Treasury Board policy). Boeing, the maker of the C17, has three plants in Canada, Winnipeg, Arnprior (Ont), and another which I cannot remember at this point. Plus, the embarrassment that the government has recently endured due to renting Antonovs only helps. I can dream....
Remember, an a/c is designed for specific missions from the start. Hercs are designed to be tac lift, and C17s are designed for the strategic airlift. I learnt this day one of Aerospace Engineering in university.
Just my two cents if anyone is listening...
