anytime.
Not much info on the upgrade, as mindef thrown a big blanket of
security over it, and is best remain that way. But I am sure being
Singaporeans, we sure KS and cramp a lot of interesting items
inside... 
Article on what I can find on the E2C upgrade.

[b]Quoting from website

The Hawkeye 2000 improvements include a mission computer upgrade
(MCU), based on commercial-off-the-shelf technology, that features
the use of advanced control indicator sets (ACISs) for
workstations. The MCU--smaller, lighter, and more powerful than
computers installed in earlier versions of the E-2C--gives the
Hawkeye 2000 a cooperative engagement capability (CEC) that
provides the aircraft the ability to fuse data from sensors of
other platforms and distribute the information to weapon-firing
platforms to permit target engagement by any platform in the net.
Hawkeye 2000 also features a new cooling system and integrated
satellite communications.
External differences in the Hawkeye 2000 include a steerable
circular end-fire array antenna mounted on the underside of the
fuselage and a conical satellite communications (SATCOM) antenna
mounted atop the rotodome. (Company officials said that a shudder
caused by the SATCOM antenna may require relocation of the antenna
elsewhere on the aircraft.)

If DTG re-wrote the source code......won't they be using another
MCU probably COTS (and super garang MIPS back then)? 
I think the displays have been changed too....color, touchscreen
etc saw a pict on a document on the Mindef website.
CEC would be a great add-on but since we are going our own way with
the data-link (at least air interface) how practical will it be to
integrate considering they won't give you the source
code.......maybe in higher OSI layers........IP link to gateways
thru SATCOM???
