The CC-115 Buffalo is currently powered by two General Electric 2,970 shp/2,214 kW CT64-410-3 turboprops
(known to the US military as T64-GE-14s). DeHavilland Canada certified civilian DHC-5E Buffalos with 3,133 shp
(2,336 kW) CT64-820-4s. The only T64 variant now in production is the 4,380 shp (3,266 kW) T64-GE-416 turboshaft for
Sikorsky CH-53 helicopters. T64 turboprops are no longer being built.
 The C-27 started life in 1970 as the T64-powered Aeritalia G.222, ten of which were sold to the USAF as
C-27As. Alenia introduced the AE2100-powered C-27J as a stablemate to the LockheedMartin C-130J. A marketing
partnership between the firms was dropped when LM unsucessfully entered its C-130J into the USAF / US Army's
troubled Joint Cargo Aircraft program in direct competition with the C-27J.
 The Rolls-Royce (formerly Allison) AE2100D3 generates 4590shp – considerably more power than the
Buffalo CT64-410-3's 2,825 shp.
 When first preparing this page, we suggested the larger PW150 turboprop as CT64 replacement. Viking Air has
now recommended the PW150 for a new-build Buffalo variant. Fitting PW150s would give a dramatic increase
in performance. That said, less powerful PW127Gs would be a less difficult fit for the nacelles. (The related PW120
is in CF service but, at 2,000 shp, isn't powerful enough for the Buffalos.)
 A CT64-820/PW127G comparison – take-off power: 2,825 shp/2,920 shp; length: 10.20"/84.00"; width 26.90/26.00";
 In 1987, to extend the useful lives of the CC-130Es, their 4,200 shp Allison T56-A-7 turboprops were
replaced with 'H model 4,591 shp T56-A-15s. 25 'E and older 'H models will be retired so
considerable stocks are available for remaining 'Hs and any potential conversions.
 Cascade Aerospace at YXX won the CC-130 Optimized Weapon System Management (OWSM) maintenance contract in October
2005. 'Herc Solutions' involves Cascade (prime contractor), Marshall's, Derco, and Standard Aero
(the existing engine contractor for CF T56s).
