WAG: E-2 as stop gap because it is assumed that this spaced based system will be ready soon. "The E-2D is far smaller than the E-7 and lacks some of its abilities, but it can fly from austere forward bases where the E-7 cannot. Tyler Rogoway, Joseph Trevithick Published Jun 11, 2025 3:36 PM EDT The proven and in-production E-7 Wedgetail, based on the Boeing 737 and serving with multiple allies, was supposed to bridge the gap between the E-3's retirement and pushing the mission to space-based distributed satellite constellations. Now, if the administration gets its wish, that won't happen. The E-7 will be cancelled and the Navy's E-2D Hawkeye will step in to fill the gap. Northrop Grumman/USAF The TWZ Newsletter A seismic shift has occurred in the Trump Administration’s new defense spending plan that is just emerging when it comes to the USAF’s airborne early warning and control (AEW&C) predicament. The service’s E-3 Sentry Airborne Warning and Control System (AWACS) aircraft are dwindling in number and rapidly aging into unsupportability. The proven and in-production E-7 Wedgetail, based on the Boeing 737 and serving with multiple allies, was supposed to bridge the gap between the E-3’s retirement and pushing the sending part of the mission to space-based distributed satellite constellations. You can read all about this here. Now, if the administration gets its wish, that won’t happen. The E-7 will be cancelled and the E-2D Hawkeye, currently flown by the U.S. Navy, will step in to fill the gap. This major turn of events came to light today as Secretary of Defense Pete Hegseth, Chairman of the Joint Chiefs of Staff U.S. Air Force Gen. John Caine, and Bryn Woollacott MacDonnell testified before the Senate Appropriations Committee. MacDonnell is Special Assistant to the Secretary of Defense and is currently performing the duties of the Under Secretary of Defense (Comptroller) and the Pentagon’s Chief Financial Officer. In 2023, the USAF announced its intention to purchase E-7s, potentially as many as 26 of them, as replacements for a portion of the E-3 fleet. A rendering of E-7 Wedgetail as it would look in USAF service. USAF At the hearing today, the question of the current future of the USAF AEW&C force came from Senator Lisa Murkowski late in the hearing. Murkowski is a Republican from Alaska, where fighters, tankers, and E-3 Sentry jets launch regularly to intercept foreign planes, primarily Russian fighters, bombers, and surveillance aircraft, over the vast arctic wilderness. Chinese H-6 missile carrier aircraft also appeared off Alaska last year for the first time, as part of a joint mission with Russia. Chinese air and naval presence in the region is only expected to grow in the future. With this in mind, just how big of an issue the age of the E-3 fleet has become was central to Murkowski’s question: “I have been concerned. We have E-3 capability up north, of course, but we were all counting on the E-7 Wedgetail coming our way. We’re kind of limping along up north right now, which is unfortunate. And the budget proposes terminating the program. Again, the E-3 fleet [is] barely operational now, and I understand the intent to shift towards the space-based – you call it the ‘air moving target indicators’ – but my concern is that you’ve got a situation where you’re not going to be able to use more duct tape to hold things together until you put this system in place. And, so, how we maintain that level of operational readiness and coverage, I’m not sure how you make it.” A US Air Force E-3 Sentry. USMC Gen. Kane replied: “You know, the E-3 and the E-3 community have been really important to us for a long, long time, and I’ll defer to the Comptroller, but I you know the Department has a bridging strategy through investing in some additional airborne platforms in order to gap fill while the space-based capabilities come online.” This is where the E-2D comes in. MacDonnell then jumped in, stating: “Ma’am, we do have in the budget $150 million in FY26 [Fiscal Year 2026] for a joint expeditionary E-2D unit with five dedicated E-2Ds, and the budget also funds for additional E-2Ds to fill the near-term gap at $1.4 billion.” Currently, the only branch of the U.S. military that operates the E-2D is the U.S. Navy. A pair of US Navy E-2D Hawkeye airborne early warning and control aircraft. Lockheed Martin The Alaskan Senator then inquired: “Can you tell me, will that have implications for what we’re seeing up north in Alaska?” Secretary Hegseth then responded: “The answer is yes. I would. I would file this entire discussion under difficult choices that we have to make. But you know, the E-7, in particular, is sort of late, more expensive and ‘gold plated,’ and so filling the gap, and then shifting to space-based ISR [intelligence, surveillance, and reconnaissance] is a portion of how we think we can do it best, considering all the challenges.” At a separate hearing before the House Appropriations Committee yesterday, Hegsteth had also described the Wedgetail as an example of a capability that is “not survivable in the modern battlefield” and mentioned broad plans “to fund existing platforms that are there more robustly and make sure they’re modernized.” An annual assessment of high-profile U.S. military procurement programs from the Government Accountability Office (GAO), a Congressional watchdog, which was released today, offers additional insight into issues with the USAF’s effort to acquire E-7s. The original plan was to acquire a pair of production representative prototype (or RP) aircraft ahead of production of examples in a finalized configuration, starting this year. The service had then expected to reach initial operational capability with the Wedgetail in 2027. A Royal Australian Air Force E-7 Wedgetail. RAAF “Air Force officials said that they now plan to begin production by the second quarter of fiscal year 2026 before completing the E-7A RP MTA [Middle Tier Acquisition] rapid prototyping effort by initiating a separate, concurrent program on the major capability acquisition pathway,” according to GAO. “They said that it was necessary to begin production concurrently with the E-7A RP rapid prototyping effort to offset the lead time associated with the build and subsequent modification of the aircraft.” “The program definitized its contract with Boeing since our last assessment. After the contract was definitized, Boeing delayed the first flight test by 9 months to May 2027,” the report adds. “According to Air Force officials, the delay was due to a late-breaking, required critical security architecture change that affected the procurement of parts, qualification testing, and modification of the airframe.” “The program stated that the Air Force definitized the MTA rapid prototyping effort contract in August 2024 to deliver two operationally capable E-7A prototype aircraft in fiscal year 2028,” GAO’s new assessment further notes. “The program added that the total acquisition cost increase of 33 percent resulted from updated methodologies to include additional scope related to non-recurring engineering, with the primary drivers being software and air vehicle subsystems.” Last year, the Air Force had been very open about the difficulties it was having finalizing a contract with Boeing for the RP jets. The two parties end up agreeing on a deal valued at nearly $2.6 billion. A contracting notice the service put out earlier this year also pointed to significant expected differences between the RP aircraft and the full production examples, including the possibility of a new radar. Existing versions of the E-7 in service elsewhere globally today are equipped with Northrop Grumman’s Multi-Role Electronically Scanned Array (MESA) radar. The USAF’s move to drop the E-7 and leverage the E-2D, which is already in the Pentagon’s stable, prompts many questions. For instance, just how many of these aircraft will the USAF end up with? As of 2024, the USAF’s E-3 fleet stood at 16 aircraft. Above all else, there are major capability trades here. The Hawkeye is a much smaller aircraft than both the Sentry and the Wedgetail. It is extremely capable, but it is also optimized to exist within the confines of carrier operations. The crew size is just five individuals. This limits the amount of shear manpower to perform highly complex operations and other tasks beyond traditional AEW&C. A trio of E-2Ds with their wings folded, underscoring their optimization for carrier-based operations. USN The E-2 is also has less range and is far slower than both the E-3 and E-7. This means longer transit times, and the aircraft doesn’t fit in as seamlessly with the jet-centric operations for the counter-air mission the service currently enjoys. The E-2D’s AN/APY-9 radar from Lockheed Martin is hugely capable, but many of its other advanced data fusion and relay systems are unique to the Navy. These systems would either be stripped or just left unused for USAF-focused operations. It’s also possible that other systems will replace them, but this will cost money and take time to integrate and field. Hawkeyes, being turboprop aircraft, also operate at lower altitudes, giving their radar, radio systems, and electronic surveillance suites reduced line-of-sight, limiting their range and fidelity at distance for some targets and surveillance application, in some cases. Then there is the aerial refueling issue. The E-2D has gained this ability relatively recently, which expands its endurance. Typical missions can now last over seven hours. However, the aircraft uses the Navy-preferred probe-and-drogue refueling method, not the boom and receptacle one favored by the USAF. The USAF’s KC-46 tankers do have a hose and drogue system and some of the service’s KC-135Rs have podded hose and drogue systems. Otherwise, they require a basket attachment to their boom, often called the ‘Iron Maiden’ or ‘Wrecking Ball,’ due to its rigid metal frame and potential to smack into and damage airframes. This system makes the KC-135R useless for refueling receptacle-equipped aircraft when it is fitted. The E-2D also refuels lower-and-slower than jet aircraft. All these issues are not ‘show-stoppers,’ but they are ones that will impact operational planning and flexibility. An E-2D moves to link up with a KC-46 tanker during a test. USN Erik Hildebrandt The E-2D, being already a highly upgraded and a much smaller airframe, also lacks the same capacity for future expansion compared to the E-7. This could include adding more personnel for various non-traditional functions, including using its advanced radar to scan the surface more extensively or for unique battle management needs, such as controlling future drone swarms, or even for more extensive passive intelligence collection and exploitation and data fusion operations. High-bandwidth datalinks can possibly make up for some of the manpower differentials, allowing folks on the ground to execute critical functions in near real time as part of a distributed crew arrangement, but there are downfalls to this concept, as well. On the other hand, having commonality with the Navy’s AEW&C aircraft should help reduce costs for both services and accelerate the type’s entry into USAF service. It could also benefit the future evolution of the E-2D as more money will be flowing into the program. It’s also a very capable and well-proven platform, lowering risk. Above all else, joint service E-2Ds could be absolutely critical to the USAF’s Agile Combat Employment (ACE) combat doctrine that will see its forces distributed to remote forward locales and constantly in motion. The E-2D’s turboprop performance, robust landing gear, and arrested landing capabilities mean it can be pushed far forward to very austere operating locations with limited runway length. And it can do this without sacrificing the quality of the data it collects or the efficacy of its use as a battle manager. This is something a 707 or 737 platform simply cannot match and could prove decisive in a major peer-state contingency. TWZ highlighted these exact benefits after U.S. Central Command (CENTCOM) released a video last year showing a Navy Hawkeye refueling from a USAF HC-130J Combat King II combat search and rescue aircraft, which can act as a probe-and-drogue tanker, primarily for helicopters and Osprey tiltrotors. While the USAF’s move away from the E-7 is certainly surprising, and it will result in shortfalls in some areas, it also unlocks new capabilities, some of which are arguably more applicable to tomorrow’s wars. It also buys down additional risk, which is looming very large as it isn’t clear at this time, at least publicly, how far along the Pentagon’s persistent space-based aircraft sensing constellation development actually is. All of this still has to make it through congressional approval, which will could be a challenge considering the special interests involved. But as it sits now, the flying service is pivoting big once again when it comes to its increasingly dire AEW&C needs."

You are understimating the Chinese. They have been doing their own designs/heavy modifications since the 60s and this plane in particular was meant to be simple and affordable, not cutting edge.

Are reserves of BMP finally starting to run out?

Were there any Cannae style battles of annihilation in the ACW at all? There's Vicksburg but The Wilderness wasn't one, neither was Fredricksburg. And at Gettysburg only a part of the AoP was involved. I think the best likely victory scenario for the Confederacy is yet another tactical victory that leaves the Union forces intact enough.

Good enough and affordable has been a great idea since the Nothrop F-5, hasn't it?

Just on the radio, Isreal has delivered Patriot systems to Ukraine. Patriot has been retired last year by the IDF.

Looks like not all was well before the 3 day operation started 3 years ago. Oh, so sad my bad.

Per reporting by Bild the shootdown of the Su-35 essentially transpired as follows: Ukrainian F-16s were hitting Russian targets with air-to-ground munitions. The Russian Su-35 moved in to attack the F-16s. However the Ukrainians had positioned an F-16 with an air-to-air load out to the side, in anticipation. It got directed by an ex-Swedish Erieye AEW&C to take a 50 km AIM-120 shot that connected with the Su-35. Shows the benefits of having AEW&C assets in play, and of the other side being decidedly short on such at the moment

Fetterman has turned out The Man. I wonder if he can secure the he D party ticket for re-election over the hard left.

Zelensky and Putin offer to mediate between Trump and Musk.

I read somewhere that the Trophy system from Israel is or will soon be available with anti drone functionality. WRT big Ukrainian "drones". https://en.m.wikipedia.org/wiki/Aeroprakt_A-22_Foxbat

The first longer video about the guy I have seen. Ok, a detachable mag is a great thing in general but that compact gun has the same capacity is a Cold War 'battle rifle'. Anyone having something about the number of shots fired in a defensive shooting? All I got is a ~30 old article saying sub compact .38s were still fine. PS: The chargers beat the hell out of C96 stripper clips!

Here's to it being true.

Just putting it out here for discussion. Pmax = k * (W^[1/3] / R)^1.13 Where: Pmax = Peak pressure at front of shock pulse from an underwater explosion. (in PSI). k = Proportionality Constant. Dependent on explosive type, but typical variations are minor, and a value of 2.16 x 10^4 for TNT (or 21,600) is “good enough”. W = Charge Weight (in pounds) R = Range from explosion (in feet) 1,100 kg charge = 2400 lbs. Lets just compromise and say that the actual charge weights placed by Budanov's Boys were 250 lbs - but there were multiples all adding up to 2400 lbs total charge weight. 250 lb charge @ 50 ft distance = 2078+ peak PSI 250 lb charge @ 25 ft distance = 4549+ peak PSI 250 lb charge @ 12.5 ft distance = 9957+ peak PSI 250 lb charge @ 6 ft distance = 22,822+ peak PSI 250 lb charge @ 0.5 ft distance = 378,300+ peak PSI Now consult the following image(s) to determine where the charge was....

Strange, it seem the smaller AWACS isn't that complicated/costly. More evidence that they really didn't expect this would be a three year war, I guess.
