    Weight saving - throw out any unnecessary equipment.

    For combat? Yes. For peacetime duties? Rely on uplink from ground radars.

    Uplink can be jammed.

    Have you even read what I wrote? How many civilian airliners you think go around carrying military-grade jamming equipment?

    I know radar is a double bladed sword. It'll help you but if not careful, it will cut you too. I see what you mean. What about the f22 radar. Difficult to detect isn't it?

    it is difficult to detect do doubt about that
    but it is also important to know that electronic capable of detecting such low level signature
    have also been developed or are under development in Europe, Russia, and China as well.

    F-22 radar is as easy to detect as anyother X-band radar. It is difficult to jam like anyother AESA radar. far too much is being made out about F-22 radar without realising that any AESA radar will have similar capabilities.
    Each T/R in an AESA can transmit at a diff frequency and they have a very short duty cycle. For jamming to be effective, the jammer must transmit whn the transmitter antenna is aligned with it and the recieve cycle opens. In AESA you have beam steering and each T/R has a separate frequency and duty cycle which can be varied randomly.

    Not that easy.....The AN/APG-77 radar, designed for air superiority and strike operations, features a low-observable, active-aperture, electronically-scanned array that can track multiple targets in any weather. The AN/APG-77 changes frequencies more than 1,000 times per second to lower interception probability. Additionally, radar emissions can be focused in an electronic-attack capability to overload enemy sensors.

    The radar's information is processed by two Raytheon Common Integrated Processor (CIP)s. Each CIP can process 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 F-22s avionics software has some 1.7 million lines of code, the majority involving processing data from the radar.[163] 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.[151] In 2007, tests 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 megabits per second and receive at gigabit speed; this is far faster than the Link 16 system used by U.S. and allied aircraft, which transfers data at just over 1 Mbit/s.[164]

    The F-22 has a threat detection and identification capability comparative with the RC-135 Rivet Joint.[151] The F-22's stealth allows it to safely operate far closer to the battlefield, compensating for the reduced capability.[151] The F-22 is capable of functioning as a "mini-AWACS", however the radar is less powerful than dedicated platforms such as the E-3 Sentry.[144] The F-22 allows its pilot to designate targets for cooperating F-15s and F-16s, and determine whether two friendly aircraft are targeting the same aircraft.[144][151] This radar system can sometimes identify targets "many times quicker than the AWACS".[151] The radar is capable of high-bandwidth data transmission; conventional radio "chatter" can be reduced via these alternative means.[151] The IEEE-1394B data bus developed for the F-22 was derived from the commercial IEEE-1394 "FireWire" bus system.[165] Sensor fusion combines data from all onboard and offboard sensors into a common view to prevent the pilot from being overwhelmed

    More difficult than older radars yes, but not enough when in combat. Modern RWRs, such as ones on Typhoon, can pick it up easily enough - and that is true for any AESA radar, not just F22s (BTW, AESA, by definition, is LPI).
