Supporting Canada's Aerospace Sector as a Vital, Strategic Industry:
The Development Potential of Bombardier's CSeries as a Case Study
Update: After several postponements, the prototype CSeries, a CS100, first flew on 16 Sept 2013. A further four CS100 'flight test vehicles' will
be completed by Bombardier for development work.
Ed: Canada's fleet of 18 CP-140 Aurora long-range maritime patrol aircraft were to be upgraded through the Aurora Incremental Modernization Project. Now that $1.6B project has been cut back. Only 10 CP-140s will go through AIMP and the
related ASLEP (Aurora Structural Life Extension Project). Although the other 8 Auroras (and 3 similar CP-140A
Arcturus ) are to be retired, the 10 AIMP aircraft are to bridge the gap until Aurora replacements arrive around 2015.
As Steve Daly notes, the leading candidate for CP-140 replacement is the Boeing
P-8 Poseidon. That US-built aircraft has just flown as a prototype but is based on an updated version of a '60s era airframe. That's not a problem in itself. Rather it is the foregone
conclusion that only foreign designs are acceptable to our Air Force that rankles. Bombardier attempted to interest DND in a maritime version of their Global Express jet (adapted from the ASTOR/Sentinel reconnaissance aircraft). That proposal apparently
received a frosty reception (although in Sept 2013, Raytheon made much the same proposal to the RAF for its Sentinel R1). Steve Daly has another proposal that answers DND/AF concerns about airframe size and adaptability – the Bombardier CSeries.
Adapting the Bombardier CSeries to replace CP-140 Auroras for Wide-Area Maritime Patrol
Canada's Department of National Defence has announced that it plans to replace the upgraded and 're-lifed' CP-140 Aurora fleet between 2015 and 2020. Defence Construction Canada
staffers are already comparing measurements of CFB Greenwood's hangars and Boeing P-8A Poseidon airframe to see what modifications will be required to accommodate this front-runner
for CP-140 replacement. As citizens, we must ask ourselves: Is the purchase of yet another foreign aircraft a wise course for Canada? Most importantly, how will this affect Canada's
Is there a domestic alternative to the foreign-sourced P-8A Poseidon? At the moment, no. None are available. But then, the P-8A Poseidon isn't available other than as a prototype
either. That airframe is based on Boeing's 737 airliner. As it happens, a domestic design has been developed to compete directly with the 737 in the commercial field.  That aircraft is Bombardier's CSeries.
Bombardier Aerospace has announced that it "is on track" to deliver its first CSeries airliner in 2013. This CSeries is to be a smaller, high-efficiency airliner offered
in two sizes, a shorter CS110 and longer CS130 (the numbers indicating passenger seat totals). Today's tougher commerical market dictates greater attention to both operating economies and reduced
maintenance burdens. Such emphasis shows that there is no reason why the CSeries airframe could not also be modified into a Canadian-built competitor to the P-8A Poseidon as
a maritime patrol aircraft.
All shorter-range airliners are designed for the higher 'cycles' of landing and taking off on multi- legged regional routes giving the aircraft built-in durability advantages over longer-range
types. To achieve its goals of lower weight and minimized maintenance, Bombardier has designed the CSeries to incorporate a large percentage of composite materials into its
airframe construction. Since composites make an airframe inherently more resistant to corrosion while flying over salt water, the CSeries will be less vulnerable than older, largely
Bombardier will also be a first-adopter with more efficient geared turbofans – the new-technology Pratt & Whitney PW1524G turbine (or GTF as this engine was previously
known). These new PW1000 series geared turbofans are vastly superior to all older-style turbofan engines (such as the P-8A's CFM56s). By comparison, PW1000 geared turbofans have
reduced carbon dioxide and nitrous oxide emissions as well as a lower specific fuel consumption.
Argus II : Support Canadian Aerospace and satisfy Canadian Maritime Patrol Requirements
There was a time when Canadian aerospace firms had little trouble in adapting the airframe of airliners into maritime patrol aircraft. Once such aerospace firm was
Canadair's CP-107 Argus was based on an existing airliner, the Bristol Britannia, but the Argus was modified almost beyond recognition for its new role.
The Argus would give Canada years of sterling service in the anti-submarine role and on sovereignty patrols. When it entered RCAF service the Argus was one of the most
advanced ASW aircraft in the world. But the legacy of Canada's Argus didn't live on.
The Canadian-built CP-107 Argus served for 24 years before being replaced by the US Lockheed CP-140 Aurora. Canadair was involved once more but, this time, in a much diminished
role. For the Aurora, only wings and a few small parts were built by Montreal for shipment to the US for assembly by Lockheed. Soon after, Canadair would be sold
to become Bombardier Aerospace.
So Bombardier has the Argus heritage to look back on and a new-technology airframe in the final stage of design. That CSeries may be beyond the dreams of designers at Canadair
in the 1950s but adapting the airframe to the maritime patrol role is a relatively straightforward if complex task. The CSeries, like all modern airliners, consists of
double-lobed fuselage with passengers above and cargo below. The lower lobe provides the ideal space for weapons bay (aft), sonobuoy launch tubes and search sensors – radar and EO/IR turret,
etc. (forward ). A composite structure simplifies placement of all other sensors.
In arrangement, our conceptual 'CP-207' Argus II follows the pattern established by both P-8A and planned Airbus maritime patrol derivatives. The purpose is not to
introduce a revolutionary new concept. Quite the reverse. The airframe is merely a 'platform' for the sensors and weapons. That being the case, why should that platform not be based on an
upcoming Canadian airframe?
Broadening the Breed: Other CSeries Military Roles – VIP and Multi-Role Tanker Transport
Of course, Bombardier designed the CSeries as an airliner. The simplest military role adaptation of all would be as a VIP transport. If this Canadian-built airframe can
fulfill the 'Canada One' role, it should do so. If a nation takes pride in its aerospace accomplishments, it must be shown. What better way to demonstrate that pride,
than in the premier place of honour in Canada's Air Force?
A CSeries VIP variant might share some common features with the Argus II maritime patrol type. Superficially, the VIP aircraft would look more like a standard airline CSeries
but the VIP variant could incorporate military fittings such as extended-range fuel tanks, observation windows, and even defensive aids. If war, as Clausewitz said, is the continuation of
diplomacy by other means then it is no surprise that aircraft meant for diplomatic or warrior roles have so much in common.
And what of the baseline CSeries for military cargo or combi (combined passengers and cargo) roles? This aircraft would not be suitable for the strategic role – the CF's larger
Airbus CC-150 Polaris fills that role. CSeries payload and range are both too limited to take over all aspects of Polaris taskings. There are, however, numerous valuable
contributions that a cargo/combi CSeries could make in CF service – including taking a load off of the Polaris fleet.
A CSeries Jack of Many Military Roles – the Multi-Role Theatre Support Tanker/Transport
There is also potential to take on another Polaris role – that of Multi-Role Tanker Transports. The Polaris MRTTs are fitted with twin inflight refuelling pods
which allow them to tank up the CF-18 fighters. This was intended to permit CF-18s to deploy overseas more easily but Polaris MRTTs also escort and refuel any CF-18s deploying
from one North American base to another.
Domestic air-to-air refuelling and fighter support tasks could be more economically handled by a smaller aircraft than Polaris MRTTs. The CSeries could form the basis for a
Theatre Support Tanker/Transport, an in-theatre analogue of the larger MRTT. Compared with an MRTT, TSTT taskings would be of a more regional nature. A CF TSTT fleet could support
operations all across North America, having sufficient range to operate from Canadian airfields to the Arctic, the Carribean, or from Pacific to Atlantic.
Adapting a closely-related airframe for both maritime patrol and transport duties also has a Canadian prescendent. The same Bristol Britannia airliner design adapted by Canadair into that
CC-107 Argus ASW aircraft was also transformed into the CC-106 Yukon. That Yukon acted as the turboprop equivalent to today's CC-150 Polaris jet-powered strategic
transport, flying both RCAF freight and passenger roles.
In the past, Canada's Air Force has also had intermediate-sized transport aircraft. One example is another Canadair adaptation – the turboprop CC-109 Cosmopolitan. The
'Cosmo' was designed as a regional airliner but had been re-engined by Canadair to have the same engines as tactical Hercules transports and Aurora patrol
aircraft. On domestic flights, the CC-109 Cosmopolitans filled a gap between smaller utility types and larger, jet-engined CC-137 Husky, a military Boeing 707 airliner. Today,
the Air Force tries to use the large Polaris to fill both roles. The CSeries is sized between the old Cosmo and the Husky and CSeries will have
advantages over both – the speed and range that CC-109s lacked and the rugged durability missing in the transatlantic 707s.
Getting There – Moving from Statements of Support to Procurement of Canadian Aerospace
It is easy to demand money for this project or that program but rather harder to deliver funds – especially in
our current economic climate. Aircraft purchases are never inexpensive these days but where is the value in our Federal Governments investing the better part of $1B in Canadian aerospace
only to turn around a spend tens of Billions on foreign-made aircraft? Sure, there are Regional Industrial Benefits but such 'offsets' do little to foster an environment
In a sense, Canada has already paid for the development of the TSTT. Being essentially 'combi' airliners, the 'Yukon IIs ' will require little further funding to realize. Developing an
all new martime patrol aircraft may seem more daunting. But, here too, the CSeries CS110 airframe development has been paid for and detail development can be both supported and
tailored by the Air Force. Under AIMP, half the CP-140 fleet is to retire. One Aurora could act as a 'CX-140' avionics testbed for the 'Argus II ',
allowing seamless integration of avionics from AIMP into the CSeries airframe. That would be the basis for a 'CP-207A' to replace the Aurora. Future avionics upgrades for a
CSeries-based 'Argus II ' would ensure Canada of a first-rate patrol aircraft for decades. A Canadian development of a Canadian aircraft in Canadian service.
The Government of Canada is paying for at least part of the development costs for the CSeries. If Bombardier knew that a TSTT variant was of interest, features could be
incorporated into the aircraft before the final design work was completed. The necessary airframe adaptations would be minimal. Other than the outer wing mounting points for
refuelling pods, there would be only superficial differences between a TSTT and a standard CSeries civilian cargo / combi transport.
In return for a little planning and a modest investment in militarizing the CSeries, Canada would gain a force multiplier and mobility aid that is the envy of our allies. Aquiring
militarized CSeries in the TSTT 'Yukon II ' guise would be a good start to long term support of Canada's aerospace industry. That support would be reinforced every time the
TSTT called in at military and civilian airfields used by the CF thoughout North America. Aquiring the complimentary maritime patrol 'Argus II ' would be an even stronger sign of
support for, and confidence in, Canada's aerospace industry and its products while also solving the CF requirement for future Aurora replacements.
 Boeing originally designed the aircraft to carry 115 passengers but that 737-100 did not sell well (only 30 were built). The -200 series was stretched to carry 130 passengers (but this variant
also included the MP Surveiller, Boeing's first attempt to produce a 737 maritime patrol variant). Later 737s carried more passengers The -800 and -900 models upon which the
P-8A Poseidon is based seat between 185 and 220. Boeing is now considering 'short ' 737s with geared turbofans.
