CRAY RESEARCH ENTERS LIGHT AIRCRAFT
INDUSTRY WITH NEW SUPERCOMPUTER SYSTEM

EAGAN, Minn., Dec. 13, 1994 -- Cray Research, Inc. (NYSE:CYR)
announced today that Raytheon Aircraft Company has ordered a
CRAY J916 supercomputer to replace the CRAY EL90 series
compact supercomputer system it installed earlier this year. 
Raytheon Aircraft, located in Wichita, Kan., is the first in the
light aircraft industry to order a CRAY J916 supercomputer
system and was the first in this industry to install a Cray
system. 

The CRAY J916 system, announced in September and slated for
first shipments in early 1995, is the new generation low-cost,
compact supercomputer system from Cray Research.

Raytheon Aircraft Company designs and manufacturers
commercial aircraft, including small commuter aircraft and
business jets.  Raytheon Aircraft engineers will use the CRAY
J916 system as they do their current Cray system to run in-
depth aerodynamic analyses of new and existing aircraft
designs.  The increased processing power of the CRAY J916
supercomputer will improve the capabilities of TRANAIR, a
NASA-developed computational fluid dynamics (CFD) program
used extensively by Raytheon Aircraft engineers to simulate
and analyze high velocity wind flow patterns around aircraft
and aircraft components during flight.

"With the new Cray supercomputer, we can do more CFD
analysis early in the design cycle which ultimately makes our
wind tunnel testing more effective," said Dr. Neal Pfeiffer,
senior technical specialist, Raytheon Aircraft.

The CRAY J916 system also will enable Raytheon Aircraft
Company to grow into other areas of aviation and
manufacturing simulation.  "The CRAY J916 will allow us to
simulate additional design areas and new tooling and
fabrication processes.  This will result in an aircraft that has
more value for our customers, and is less expensive for us to
produce," according to David Bernsdorf, Manager, Special
Projects at Raytheon Aircraft.

The new CRAY J916 supercomputers are scalable, UNIX-based
servers with four to 16 processors. The CRAY J916
supercomputer is the third generation of Cray Research
systems priced beginning well under $1 million.  The company
has recorded more than 250 orders for these low-cost systems
since entering the market in late 1991.

Cray Research provides the leading supercomputing tools and
services to help solve customers' most challenging problems.
