Strategic Airlifters: a Comprehensive Comparison between the Boeing C-17 and the Antonov An-124-100   [Part 2]

Dispelling Myths About the Antonov An-124-100

There is a very serious misconception about the An-124-100  –  namely, that it is an old, inefficient, clumsy, Soviet-built military aircraft.  [Ed:  the original An-124 Condor, which first flew in Dec 1982, was a military transport but it was anything but clumsy or inefficient.]  In fact, the An-124-100 is a fully commercial derivative ( the world’s largest commercial air freighter ) with more than 14 years experience of intensive, global commercial operations. The civil An-124-100 was certified in 1992, a year after the supposedly super-modern Boeing C-17 first flew. [1]

The An-124-100 meets all current civil standards, including ICAO Stage/ Chapter III noise limits and modern navigational equipment requirements. It has improved performance engines, Western avionics, and is equipped with VHF radios, TCAS [or Traffic alerting and Collision Avoidance System] and RNAV [aRea Navigation which computes actual aircraft position/speeds relative to a selected flight route].

The estimated service life for the An-124-100, both in terms of its operational life and in the anticipation of the obsolescence of its technology and design, is fifty years.  It is projected to have at least twenty-five years of operation without any major repairs. The An-124-100 is a truly unique plane with unique capabilities  – that is why it has become such an unrivalled success in the international market.

As a conclusion, the An-124-100 out-performs the C-17. Much of the Antonov’s technology is on par with that of the “state-of-the-art” Boeing C-17 aircraft, lying within the strictest technological requirements of modern aviation.

Financial Aspects: Acquisition versus Guaranteed Access to Capability

[Ed: All figures are given in US dollars. Note that, for accounting reasons, prices for USAF C-17As are usually quoted in constant, Fiscal Year 1998 US dollars.]

We will compare the costs of different acquisition models:  lease, purchase, and assured chartering.

Boeing C-17 Globemaster III

How much does it actually cost to purchase or to lease a C-17?  We have some historical evidence about C-17 unit costs.  In 2000, the UK’s Ministry of  Defence  (MoD)  signed a ‘lease-and-support’  agreement with  Boeing and the United States Air Force for the use of  four  Boeing C-17s  ( three + one “active reserve” ) for the period 2001 to 2007.

The price was  US $750M  for the lease and  US $400M  for support arrangements (maintenance, training, services etc).  The total cost was thus US $1.15B.

Based on this British precedent, a 7-year lease of  six  (6)  C-17s for the Canadian Forces would cost at least US $1.725B [US $1.15B ÷ 4 = US $287.5M per aircraft x 6 aircraft = US $1.725B] or  Cdn $2.0B. Thus, Canada would pay about $333M per aircraft in total, or $47.6M per aircraft, per year (assuming a 0.8584 exchange rate).

This is, of course,  if we are talking about a 7-year lease only  –  not the purchase price.  In the case of an outright purchase, the price would be higher.  According to Boeing data, USAF C-17 purchase prices range from  US $175M  to  US $232M.

[Ed:  the USAF cite unit costs of  FY1998 constant US $236.7M.  A 2002 contract for 60 more C-17s dropped  to US $161M  per aircraft  due to order size and cost- controlling measures. Note that the USAF costs generally do not reflect complete aircraft  –  the US government furnishes some C-17 components and equipment.]

Antonov An-124-100

Only 2 An-124-100s are required to carry the loads of 4 C-17s, or 3 An-124-100 to carry loads equivalent to 6 C-17s.  Thus, we see an economy of scale advantage.

The purchase price for the An-124-100 is about US $25M  –  approximately 15% of the  C-17  purchase price (at an averaged US $185M ).  But,  the CF will need fewer An-124s  than  C-17s.  So,  based on cost and capacity,  or a value comparison,  the An-124-100 price is equivalent to 7.5% of the purchase price of  a new Boeing C-17.

[Ed:  Boeing now seems to have fixed the C-17’s price at US $220M per aircraft .]

A conventional ‘standby lease’ for one An-124-100  ( 1000 hours a year  –  at full standby option) is US $5M per year or 12% of the C-17 aircraft lease price. Based on the above capacity-for-value reasoning, an An-124-100 lease price amounts to only 6% of the C-17 lease price.

A third option is the so-called ‘assured chartering’ or ‘partial lease’. This is based on a maximum of 500 hours per year  –  a more realistic upper limit to annual needs for strategic airlift by the Canadian Forces. This lease arrangement would amount to approximately US $2.5M per year, or only 3% of the C-17 lease price.
[1] Ed: Design work on the C-17  (originally the C-X ) began in 1980.  The concept was derived from the 1970s-vintage McDonnell Douglas YC-15 prototype airlifter.
