A FEW MORE QUESTIONS ABOUT "Our North, Strong and Free" HELICOPTERS, WHAT HELICOPTERS?



In their latest Defence policy "Our North, Strong and Free: A Renewed Vision for Canada’s Defence" the government announced that they would " provide the Canadian Armed Forces with the speed and airlift capacity to assert Canada’s sovereignty and respond to natural disasters and emergencies throughout the country, we will acquire a more modern, mobile and effective tactical helicopter capability."

There are several obvious candidates to fill the tactical helicopter role for the Canadian Armed Forces.

One would be the Bell UH-1Y "Venom". The Bell UH-1Y is a twin-engine, medium-sized utility helicopter built by Bell Helicopter as one of the latest members of the numerous Huey family of helicopters, a family which includes the Bell CH-146 "Griffon", the current tactical helicopter used by the Canadian Armed Forces. 

As an evolved version of the aircraft currently in use it would be a natural and comparatively easy transition for pilots and maintainers.  As it is currently in service with the U.S. Marines it can be expected to be in service for many years with spares, upgrades, and even doctrine being easily available. Costs for both initial purchase and maintenance should also be relatively straight forward given U.S. experience.

The other obvious choice to fill the role would be some variant of the Sikorsky UH-60 Black Hawk. In wide spread use in a number of countries as well as the U.S. Army, it is in production with upgrades and spares available for decades to come. Sharing engine commonality with the currently in service Sikorsky CH-148 Cyclone it would a safe and cost effective choice.


Another reasonable choice to fill the role of a modern, mobile and effective tactical helicopter capability would be a troop carrying variant of the CH-148 Cyclone. Currently in service with the RCAF, the CH-148 is a military variant of the Sikorsky S-92 designed for shipboard operations, it replaced, after much time and money was spent, the CH-124 Sea King.


The H-92 is the military version of the S-92 from which the CH-148 is derived. In the utility transport role it is capable of carrying 22 troops and can also be configured for specific missions, including search and rescue and executive transportation. The choice of a CH-148 variant to fill the role would bring the commonality of spares, equipment and even training that comes with a bigger fleet. This acquisition, with its concomitant savings, could even include a few aircraft, configured for search and rescue, to augment our hard worked and under resourced CH-149 Cormorant SAR fleet.


A less likely but still viable choice would be to purchase more CH-147 heavy lift helicopters. In 2009, Canada signed a contract for 15 of the F model of the aircraft which, inevitably and at great expense, were extensively modified and upgraded for the Canadian Forces, they were delivered in 2013–2014 with the Canadian designation CH-147F.

While not thought of as a 'tactical' helicopter they are often used as such. More to the point, heavy lift helicopters are almost a national asset, as useful for disaster relief as they are for logistic support, you really can't have enough of them. While such a procurement might seem more expensive, in terms of initial purchase cost, savings would be found in the commonality with an existing fleet and its attendant logistics and training infrastructure.


If a purchase of CH-147 Chinook helicopters was paired with a purchase of Bell 429 'Global Rangers' , the same aircraft in service with the Canadian Coast Guard, to be used as a more economically viable aircraft for the purely utility role, there could be further savings. It doesn't hurt that these useful aircraft are manufactured in Canada.

All of the above would be viable choices for the Government intention to "acquire a more modern, mobile and effective tactical helicopter capability" which they suggest in the new Defence policy is a priority. If the procurement was pursued with any sense of urgency the aircraft could be in service within five years at an affordable price.

This will not happen. In five years the Department of National Defence will announce that they are five years away from an option which involves a bespoke aircraft, highly modified for Canadian use and in service no where else in the world which costs twice as much as any of the above options. They will be mistaken, it will take twice as long as predicted and cost three times more then it should.

This last is not a cynical prediction, based on all previous performance and the lack of any real change in our procurement policies, it is a fact.

CORMORANT MID-LIFE UPDATE, A MISSED OPPORTUNITY


On May 24th of this year the federal government notified industry of a sole source deal to modernize its Cormorant search-and-rescue helicopter fleet. The agreement is with Leonardo, the Italian aerospace firm whose subsidiaries originally built the CH-149 Cormorants.

Leonardo had proposed that the existing 14 Cormorants be modernized and in addition they suggested that seven of the nine presidential VH-71 helicopters, a variant of the company’s EH-101 helicopter purchased from the U.S. in 2011 for spare parts, could be put into service for search and rescue operations. Parts obtained from those same helicopters have played a critical role in keeping the RCAF Cormorants flying.

There was no cost attached to the plan but a previous estimate on the upgrade put the price-tag anywhere between $500 million to $1.5 billion. That original project, known as the Cormorant Mid-Life Upgrade (CMLU), did not specify that the eventual solution had to be a Cormorant. Despite the name other helicopter manufacturers believed there was an opportunity to meet the Royal Canadian Air Force (RCAF) requirements with aircraft they believe could be more effective and efficient.

Sikorsky offered Canada its S-92 civilian helicopter for the Royal Canadian Air Force’s search and rescue operations, making a case that it would be less expensive to buy new rather than upgrade the existing fleet of Cormorants. Sikorsky believed that the solution they proposed would be more affordable at acquisition and throughout the entirety of the life-cycle.

They pointed out that the S-92 has a high mission-readiness rate, the latest in de-icing technology and can operate in extreme temperature conditions. As well, Sikorsky representatives pointed out that S-92s are used by the Irish Coast Guard, the South Korean Coast Guard and in the United Kingdom for search and rescue and other missions.

Based on third-party analysis of U.K. SAR data, Sikorsky also claims to be “at least 50 percent of the cost per hour to operate the S-92 compared to the incumbent,”

Sikorsky assumed that part of the appeal of their offer would be that the Royal Canadian Air Force is currently introducing into service the Cyclone maritime helicopter. The CH-148 Cyclone, a militarized variant of the S-92, will reach initial operating capability with the Royal Canadian Navy later this year, and could serve as a reason to develop some common aircrew and technician training. Compatibility between the SAR and maritime helicopters might also improve fleet management.

It is reported that Department of National Defence sources say that it was determined that it would be "more cost effective to stay with the Cormorant fleet as it is a proven aircraft the RCAF knows well". The RCAF also hopes to purchase a simulator for the Cormorant fleet to help train crews.

This decision by the Air Force, to refurbish and update the Cormorant fleet, makes no sense. If the RCAF were to take their conclusion, that is “more cost effective to stay with the Cormorant fleet as it is a proven aircraft the RCAF knows well” to its logical end then it would never purchase any new aircraft of any kind.

Even more importantly this choice represents a lost opportunity to reduce the number of aircraft types in service with that service. Instead of operating just three fleets of complementary helicopters, that is CH-146 Griffons, CH-147 Chinooks and CH-148 Cyclones, along with a search and rescue derivative of the latter type; by the including CH-149 Cormorant in their fleet they will have four types in service .

In its comparative analysis of options regarding a single or mixed fleet for the National Fighter Procurement program the Air Force found that “the cost of duplication may result in a mixed fleet that is more expensive than its single fleet”.
Further their studies showed that “In the case of a mixed fleet, extra costs result from duplication: infrastructure; aircraft maintenance support equipment; operational and maintenance training; supply lines; project management; engineering support; aircraft certification; test and evaluation; storage and management of spare parts, weapons, and expendables; and electronic warfare and systems reprogramming are just some of the many sources of duplication”.

There is no reason to believe that the same logic that drives the Air Force to prefer a single type of fighter should not apply to other kinds of aircraft. Sikorsky is not suggesting an entirely new type of helicopter to replace the Cormorants. What is being proposed is an opportunity to rationalize the number of kinds of aircraft used, with all the accompanying savings in “infrastructure; aircraft maintenance support equipment; operational and maintenance training; supply lines; project management; engineering support; aircraft certification; test and evaluation; storage and management of spare parts, weapons, and expendables; and electronic warfare and systems reprogramming”.

There may be reasons the RCAF has decided to pass on the chance to save taxpayer money and increase their own effectiveness. Perhaps they are motivate by their previous experiences dealing with Sikorsky, perhaps the people in the CH-148 office don’t get along with the ones in the CH-149 department, probably they know somethings we don’t. Anything is possible. What is not acceptable is that this decision is being made with no attempt to explain to the public why the choice has been made to commit to operating more types of aircraft at greater expense. The stated reasoning, that it will lead to better Search and Rescue outcomes, does not stand up to analysis.
