EL SEGUNDO, Calif.--(BUSINESS WIRE)--Aug. 4, 1995--The first of a new generation, integrated processor that will serve as the ''brains'' of all the avionics for the F-22 Air Superiority Fighter, was delivered by Hughes Aircraft Co. to Westinghouse Electric Co. Wednesday.
...''Our design, based on more than 30 years of pioneering work in providing processors for the United States' front-line tactical aircraft, jams the equivalent of two Cray supercomputers into two packages that combined are only a little larger than a 20-inch portable color TV.
The radar's information is processed by two Raytheon Common Integrated Processor (CIP)s. Each CIP operates at 10.5 billion instructions per second and has 300 megabytes of memory. Information can be gathered from the radar and other onboard and offboard systems, filtered by the CIP, and offered in easy-to-digest ways on several cockpit displays, enabling the pilot to remain on top of complicated situations. The Raptor’s software is composed of over 1.7 million lines of code, most of which concerns processing data from the radar. The radar has an estimated range of 125-150 miles, though planned upgrades will allow a range of 250 miles (400 km) or more in narrow beams. In 2007, tests carried out by Northrop Grumman, Lockheed Martin, and L-3 Communications enabled the AESA system of a Raptor to act like a WiFi access point, able to transmit data at 548 Megabit/sec and receive at Gigabit speed; far faster than the current Link 16 system used by US and allied aircraft, which transfers data at just over 1 Megabit/sec.
The T3E initially used the DEC Alpha 21164 (EV5) microprocessor and was designed to scale from 8 to 2,176 Processing Elements (PEs). Each PE had between 64 MB and 2 GB of DRAM and a 6-way interconnect router with a payload bandwidth of 480 MB/s in each direction. Unlike many other MPP systems, including the T3D, the T3E was fully self-hosted and ran the UNICOS/mk distributed operating system with a GigaRing I/O subsystem integrated into the torus for network, disk and tape I/O.

It's an Aircraft.
Having a Supercomputer on board is ridiculous.
IT is nearly impossible to actually have as much data going through the ships systems that would actually necessitate a multi Gflop CPU.
ITs completely unnecessary.
i think using the kalashnikov in the comparison is unfair to the kalashnikov; for while the gun is a masterpiece, the planes are not.
and the quaint plane that Edrick is proposing (w/o or with lesser computers, etc) would be like an ordinary telescopic sight, while the F-22 would be more akin to the hubble space telescope.
in the F-22, those same computers analyzes the returns as it acquires and confirms the target.
The Raptor’s software is composed of over 1.7 million lines of code...
Windows NT 3.1, 4-5 million lines of code
Windows NT 3.5, 7-8 million lines of code
Windows NT 4.0, 11-12 million lines of code
Windows 2000, 29+ million lines of code
Windows XP, 40 million lines of code
Windows Server 2003, 50 million lines of code

Odds are, that the OS the Raptor uses is not going to be able to do the following:
etc, etc, etc...
modern pc`s put out over 40 GFlops -
