http://www.janes.com/article/71285/orbital-atk-firms-up-aargm-er-design-conceptOrbital ATK's ER solution features a number of design changes to the existing AARGM configuration and leverages what Mike Stuart, Orbital ATK's director of missiles strategy, business development and marketing, characterises as "higher technical readiness level (TRL) subcomponents with reduced risk, to accelerate the timeline to the US Navy customer".
"From our design concept perspective, we took a look at the threats, we took a look at, most importantly, the ranges that we thought were going to be needed, and then we wanted to bring in technology associated with achieving those goals, that were higher TRL," Stuart told Jane's .
The Orbital ATK design introduces an aft actuator control system with the mid-body wings on the legacy AARGM removed. This not only enables a form fit capability internal to the F-35 but also improves manoeuvrability and reduces drag, Stuart said. The company has introduced side-body strakes that deliver lift during the missile's flight.
To assist the required range increment, the existing mid-body control section componentry is repackaged to deliver additional space for propulsion, while the airframe is tapered up from aft of the seeker section to deliver an approximate 10% increase in diameter, with consequent additional volume for propulsion.
Stuart said the company is evaluating multiple sources for the aft actuator solution and also for the new rocket motor design that, Jane's understands, is expected to deliver an engagement speed that is double that of the current AARGM. "Our assessment is that there are propulsion options out there that are high TRL and can quickly transition into a production scenario to meet the USN's timelines," he said.
While the propulsion type has yet to be decided, a ramjet solution has not been discounted. "The current Orbital ATK design concept is not a ramjet, but it certainly doesn't remove that potential. However, it will be the USN and its requirements office that make the final decision on where they want to go with propulsion," he said.
'Increased Survivability' is built into the AARGM ER requirement, although Stuart declined to comment on the specifics of the Orbital ATK solution, noting only that "speed is in the equation. We're going double the range in about the same amount of time, and you have to increase speed to achieve that; so speed in and of itself is an improvement to survivability. There are other aspects of our design solution that improve survivability, but these are not releasable".
The Fiscal Year 2018 President's Budget requests $6.4 million of RDT&E,N for High-Speed Anti-Radiation Missile (HARM) and AARGM Foreign Material Assessment; $15.2M for AARGM to implement M Code, transition receiver upgrade from ONR efforts and Block 1 follow-on development; $66.3 million of RDT&E,N for AARGM Extended Range (AARGM-ER) development; and $183.4 million of WPN for production of AARGM modification kits for 251 All-Up-Rounds and Captive Training Missiles. The AARGM cooperative program with the Italian Air Force transforms the HARM into an affordable, lethal, and flexible time-sensitive strike weapon system for conducting Destruction of Enemy Air Defense missions. AARGM adds multi-spectral targeting capability and targeting geospecificity to its supersonic fly-out to destroy sophisticated enemy air defenses and expands upon the HARM target set. The program achieved IOC on the F/A-18C/D aircraft in July 2012, with forward deployment to PACOM; integration is complete for AARGM with release of H-8 System Configuration Set for F/A-18E/F and EA-18G aircraft. The AARGM Block 1 software only update will achieve IOC the third quarter of FY 2017. The AARGM-ER modification program, involving hardware and software improvements, began in Fiscal Year 2016. This effort will increase the weapon system's survivability against complex and emerging threat systems and affords greater stand-off range for the launch platform. AARGM-ER will be designed to fit internally in both the F-35A and F-35C, thereby increasing the capability and lethality of the Lightening II weapon system.

Probably that the SEAD Roadmap said AARGM-ER would be a full and open competition but they actually awarded it sole-source to NG (who just bought Orbital ATK).sferrin said:

Would the VFDR fit internally in the F-35? Isn't that a requirement for AARGM-ER? Or am I mistaken?marauder2048 said:The VFDR stack from T3; it was at the requisite level of maturity. That the IOC date has now slipped two years undermines

I find it hard to believe that motor is an end-burner given it only fired for about 10 seconds. (Unless they've found a way to REALLY increase the burn rate, but then what does that do to the ISP?)marauder2048 said:
It was a sincere question. I honestly don't know enough about that VFDR stack to know its origins or what aircraft it was designed to fit. There were older airbreathing HARM/AARGM concepts that probably would not have fit.bring_it_on said:Given it was supposed to work on the F-22 and F-35 as a future BVRAAM why would you think that a design leveraging that propulsion option wouldn't be compliant with the F-35?
The SiAW adds a universal armament interface, a new warhead and fuze combination and integration on Lockheed Martin’s single-engined stealth fighter, Air Force budget documents show.
The Air Force has budgeted $860 million to spend between fiscal 2018 and 2024 on research and development for the SiAW program. Over the same period, the Navy’s AARGM-ER program office is contributing $443 million to the development phase.
Stand In Attack Weapon (SiAW) system will provide strike capability to defeat rapidly relocatable targets that create the Anti-Access/Area Denial (A2/AD) environment.
The target environment includes Theater Ballistic Missile Launchers, Land Attack and Anti-Ship Cruise Missile Launchers, GPS Jammers, Anti-Satellite Systems,
and Integrated Air Defense Systems. Key attributes of the Stand-in Attack Weapon (SiAW) will include Lethality, Responsiveness, Survivability, Range, and Internal
Carriage. The F-35 is the Air Force threshold platform. The path to the SiAW capability is through the Navy Advanced Anti-Radiation Guided Missile-Extended Range
(AARGM-ER) program with additions to the Universal Armament Interface (UAI), Warhead/Fuze, and Integration on the F-35. SiAW was a FY18 new start. New start
activities initiated program stand-up, facility upgrades, program office support, and other analysis support to include UAI, Mission Planning, Test Planning and Range
Infrastructure requirements, and future test and integration on the F-35.

New Missile Prepares for F-35 Tests
20 Feb 2020 Rachel S. Cohen
"The Air Force is moving forward with its Stand-In Attack Weapon, preparing to check how it fits inside the F-35 Joint Strike Fighter this summer. Though the service previously said the missile would fly on the B-21 as well, Air Force spokeswoman Ilka Cole said recently the F-35 is now the only USAF aircraft under consideration. Fit checks will entail wind tunnel testing and ground tests.
The weapon is based on the extended-range version of the Navy’s Advanced Anti-Radiation Guided Missile in development at Northrop Grumman. Cole said missile design specifications like its range are classified....
...“SiAW targets include theater ballistic missile launchers, land attack and anti-ship cruise missile launchers, GPS jammers, anti-satellite systems, and integrated air defense systems,” according to Air Force budget documents...
...The baseline version [AARGM] is already integrated onto the F-35. Military testers will vet the SiAW on the F-35 in the early 2020s so it can begin regular operations by the mid-2020s. It’s expected to wield a new warhead, the design of which is slated to end in fiscal 2021.
The Air Force created the program in 2018 and requested $160.4 million for SiAW development in its 2021 budget, ramping up to $364.5 million in 2025. The request did not say how much the weapon will cost in total."
