“With a second trip to Australia under my belt this Summer and a chance to talk with the RAAF’s Surveillance and Response Group as well as Air Marshal Davies, Air Vice Marshal MacDonald and the recently retired Air Marshal Brown, I began to understand how the “troubled” program had not only been “salvaged” but how it was “salvaged” put in the trailblazing path.
“The Wedgetail has brought to the fight, unique battle management capabilities. To understand what they mean, one has to look at some of the Wedgetail’s core capabilities.
“Most fundamentally, the Wedgetail does not operate like an AWACs. The AWACs works in tracks directing the air battle but does so with a 360-degree rotating radar. It is the hub of a hub and spoke air combat system.
“With the coming of the fifth-generation aircraft, there is a need for air battle management, but not of the hub and spoke kind. And with the challenge of operating in the expanded battlespace, it is not simply a question of management of air assets, but management of the assets operating in the expanded battlespace, regardless if they are air, naval or ground….
“It is designed with the reach rather than range approach characteristic of fifth generation systems; the MESA radar can be dialed up in terms of energy and focused in terms of direction on priority scan areas.
“As one Northrop Grumman engineer put it: “There is a fundamental shift operationally in terms of how one uses the Wedgetail versus the AWACS. You no longer are limited or defined by a 360-degree rotator.
“You are able to configure how much power you want to put into your radar reach; it is configurable to the mission. The integrated IFF and radar functionality also allows the system to reach much greater than other systems into the battlespace to shape greater situational awareness in the battlespace. You can put the energy in the mission area where you have the highest priority.”
“This allows much greater reach, and is also part of enhanced survivability as well.
“This means as well that it can act on demands identified by deployed fifth generation and other aircraft with regard to the areas where extended reach and focus for surveillance needs to be directed.”

El secretario Frank Kendall declaró recientemente que la Fuerza Aérea ha tenido “dificultades” para llegar a un acuerdo sobre el contrato de coste incrementado del E-7A Wedgetail, fabricado por Boeing. Hunter dijo a los periodistas que el servicio está “trabajando con [Boeing] para llegar a un precio asequible” y que las dos partes han “reducido significativamente” las diferencias, pero “todavía no hemos llegado”.

Esta vez en concreto las versiones de seguimiento de pruebas de misiles balísticos y tácticos.

Ese avin que prueba la Navy ser para sus misiones litorales, la USAF dice por activo y por pasivo que UAV y plataforma espaciales.
Puede ser que converjan en un mismo programa, pero no parece que vayan por ese camino en publicaciones oficiales o especiales.
The Air Force, heavily constrained by budgetary shortages, cancelled the E-10 Multi-Sensor Command and Control Aircraft program in 2006. The E-10 would have added a highly advanced airborne battle management command and control asset to the Air Force fleet. Its cancellation reinforced the need for AWACS to continue performing at the highest possible level.

Increment 1 of the Air Force evolutionary acquisition program for the E-10A provided for a cruise missile defense and advanced airborne ground surveillance and targeting capability. The E-10A would include the Northrop Grumman/Raytheon Multi-Platform Radar Technology Insertion Program (MP-RTIP) radar and an advanced Battle Management Command and Control (BMC2) subsystem integrated on a Boeing 767-400ER aircraft
[...]
The E-10 MC2A [Multi-Sensor Command and Control Aircraft] was designed provide ground, and selected airborne, moving target indication, as well as key battle management command and control and was expected to be a central element in the Air Force's Command and Control Constellation.

The E-10As MP-RTIP radar was designed as a modular, scalable, two-dimensional active electronically scanned radar. The MP-RTIP also supported the Global Hawk program. MP-RTIP would deliver a large sensor variant for the E-10A aircraft and a "small sensor" variant for the Global Hawk.
The MP-RTIP is a modular, active electronically scanned array radar system designed to be scaled in size in order to fit on board different platforms.
The Air Force's MP-RTIP program is developing a modular, active electronically scanned array (AESA) radar system scalable for different aircraft -- specifically for the Global Hawk [...]

The MP-RTIP radar that Northrop Grumman and Raytheon are developing will be able to track slow-moving ground vehicles and low-flying cruise missiles. Compared with existing ground-surveillance radar systems, the MP-RTIP will have enhanced resolution and will be able to collect ground moving target indicator imagery and synthetic aperture radar still images simultaneously.
MP-RTIP (Multi-Platform Radar Technology Insertion Program) is an airborne surveillance radar operating in X-band for long-range surveillance of fixed and moving targets. The radar uses Ground Moving Target Indicator (GMTI), Synthetic Aperture Radar (SAR), Air Track, Concurrent Moving Target Indication, Cued Search, and Ground High-Resolution Radar modes of operation. The MP-RTIP is designated AN/ZPY-2 in the U.S. Air Force. The sensor consists of three main assemblies. These are the antenna, the radio frequency electronics, and the radar signal processor. The antenna is an active electronically scanned array (AESA), which consists of 1800 radiating elements. It can be mechanically rotated in the longitudinal axis to point either left or right of the flight direction.
The Challenger: Raytheons P-3C LSRS & Boeing P-8 AAS
Raytheons AN/APS-149(V) Littoral Surveillance Radar System (LSRS) is a classified and little-known surveillance radar that was first seen by the public in 2007, mounted on US Navy P-3C Orion maritime patrol aircraft (MPAs). Its ventral canoe antenna, and reported capabilities, are equivalent to those of Northrop Grummans earlier AN/APY-3 JSTARS radar, and include a primary targeting capability. Seven radars had already been delivered by mid-2007, with 16 modified Orions reportedly capable of carrying the radar. Though some AAS-related contracts have been announced, the program has never had an unclassified budget line or documentation. None of its elements have reportedly been competed or subjected to a formal analysis of alternatives process.

The AAS radar will not be built for every P-8A, but the Navy has already spent big money just to determine how many to buy.
The United Kingdom and India have already swallowed their pride and taken the easy way out by buying Poseidons for MPA, instead of investing billions of dollars to develop their own solution (aka, Nimrod replacement). We forecast the UK will likely follow on with substantial Raytheon AAS radar purchases in the future to replace their recently retired (March 2021) Sentinel R.1 aircraft fleet which carried the also-Raytheon ASTOR radar
[...]
And Australia, Norway, New Zealand, Korea, and others are also buying Poseidon fleets. Buying a number of AAS-equipped Poseidons will be a cheap and easy way to add a hugely valuable overland capability to many air forces.
So what was the Air Force problem with Poseidon/AAS for JSTARS Recap???
Well, Teal Group believes the Air Force is simply too parochial to allow the Navy to take over (or provide the aircraft for) their overland JSTARS/airborne ISR/C4I mission. In fact, some of the continued classified status for the LSRS and AAS radar programs could even be to avoid making it too obvious that the Navy is just as good (or now, with AAS, better) at this mission as the Air Forces old JSTARS. Since the Navy has also largely avoided criticizing the late, expensive F-35 JSF while at the same time buying as few as possible and recently extending their F/A-18E/F Super Hornet buy for another several years/hundred aircraft
