Singapore E-2C Hawkeye replacement
-
The UK uses E-3 only. The nimrod project was cancelled when their software cannot distingush between cars on the expressway and low flying helicopters. Something to do with basic design and software.Originally posted by duotiga83:UK uses both E-3(being NATO) and nimrod
E-3 AWACS (Airborne Warning And Control System)
E-2C AEW (Airborne Early Warning)
Each perform different role. I am sure other posters can do a better job than me digging up the links.
Note there is a future path to all these, J-Stars. -
I know, whatÂ’s my point is even the world No1 is just getting its E-2C fleet upgraded to 2000 standard and not lavish enough to replace it. So the talking of replacement is unrealistic, RSAF always can upgrade the E2C as well. Especially other countries in the Asean even donÂ’t have a taste of AWES as yet.Originally posted by insouciant:Because the technology on our Hawkeyes are getting old. The US versions were upgraded and may be upgraded again.
....Whatever happened to RSAF's study of replacing the Hawkeyes with long endurance UAVs? -
It costed Sg an amount equal to the then annual defense
budget to buy the four 4 E2C,around 1986.Some US$800m.
But Not an old E2C anymore!

Has the Sg E2C been upgraded to Group 2?DSTA did in replacing the Mission Control System of the E-2C. Basically, the brains behind the E-2C. We introduced new and more powerful computers, developed the real-time command and control software and introduced high resolution colour monitors. We've also incorporated the satellite-based Global Positioning System or GPS for short."

"Basically, it's a radar that allows the E-2C to provide automatic detection and tracking a target over water and over land up to 250 nautical miles away. In addition to the APS 138 Radar, what the E2 carries is the identification friend or foe system. Now this allows the weapon system officer on board the E-2C to identify the target meaning that he'll classify them as either friendly or unknown up to 250 miles away."
capable of providing air and surface surveillance, as well as tactical control of air assets....
within DSTA, we were able to design and develop the Command and Control (C2) system and its software (completely) locally.

4.Prof Lui Pao Chuen, Chief Defence Scientist,
Naval Platform Technology Seminar 10th May 2001 tell you
what is LALEE38. A UAV designed for a continuous coverage mission will require the operating cost per flying hour to be very low, below US$1,000, to be affordable. A continuous coverage station will require the flying of about 10,000 hours per year. The capital cost of acquiring the platform and payload, say at US$50m will be overtaken by the operations and maintenance cost after five years of operations. The US Navy is studying the MRE (Multi-Role Endurance) UAV to perform this mission. We have just completed a 3 year long study of LALEE which is an integrated airborne surveillance and communications system designed to provide continuous temporal coverage over a very large area. Providing a task group operating in the littorals with continuous surveillance from the air with this class of UAV will be considerably cheaper than operating current generation of surveillance and communications platforms. The technology is there but whether Navies will to want to invest in this class of UAV will depend on their perceived need for a continuous coverage platform.

A UAV AEW may not be as good... True, it may be cheaper a bit... but thats still quite a lot of technology u're gonna put up into the air on a very small platform. If something was to malfunction, perhaps a slight one... still have to retrieve the UAV and send another one up.
On an aircraft like the E-3, there can still be technicians and engineers on board to enhance mission endurance.
E-2C, well, i think its the air frame that needs to be replaced. It is a very old aircraft. Aircraft materials are subject to high stresses, and its wear and tear could lead to serious accidents. There is a limit to how long u can fly something safely... -
Then I believe the G550s will take over.Originally posted by Shotgun:A UAV AEW may not be as good...

Thats true. An old tank can still run and an old ship can still float, just move slower and with more problems. However, an old aircraft will crash!

rather than any other system. Like what lionnoisy had said, the mission computers are upgraded. Our E-2C are not ordinary E-2C, shld be E-2C+ 
. But in terms of age wise, the almost 20 years frame can be the main trouble if there is not enough visual inspection.
