Increasingly,
Rolls-Royce Tay, BR710, & Spey powered aircraft
are being outfitted for a variety of special mission
applications such as electronic intelligence,
maritime and border patrol, airways navigation
verification, logistics support and photo reconnaissance.
For example, in 2001 Saudi Arabia received its
first special mission Tay 611-8 powered Gulfstream
GIV-SP equipped for medical evacuation. The Gulfstream
GIV and GIV-SP are widely used for special mission
purposes, with more than 50 aircraft in service
with governments world wide.
The Tay 611-8 is renowned for its reliability.
An improved version of the engine is under development.
The new engine mark designated Tay 611-8C includes
the incorporation of an electronic engine control
system (FADEC).
This latest Tay edition is aimed at the continuation
of the record reliability set over the last 40
years by the preceding Rolls-Royce powered Gulfstream
GI (Dart powered), GII, and GIII (Spey powered).
