Ultra Hornet
By Graham Warwick
Boeing and the US Navy are poised to expand and exploit the F/A-18E/F Super Hornet's capability for precision engagement and battle management now the upgraded platform is matched to the latest avionics
While debate rages over the hallmarks and advantages of fifth-generation fighters, Boeing is preparing to deliver the next generation of its long-running F/A-18. The F/A-18E/F Block II+ Super Hornet is the culmination of a fundamental upgrade of the multi-role fighter and the foundation for future capability expansion.
Next-generation Super Hornet deliveries to the US Navy will begin later this year when the first aircraft from production Lot 30 rolls off the St Louis, Missouri assembly line. "Lot 30 is the launch point for Block II+," says Kory Mathews, director of F/A-18 programme integration.
Today's F/A-18E/F Super Hornet was developed from the original F/A-18 Hornet in two stages: first an airframe and engine upgrade that scaled the fighter up by 25% to increase range, payload and growth capacity then a multi-phase avionics update that introduced advanced sensors.
Lot 30 is the first time the structural upgrade that produced the F/A-18E/F comes together with the full suite of advanced avionics, and is the jumping-off point for the Capability Flightplan - a roadmap of enhancements planned to be developed and fielded over the next decade.
Robust roadmap
"We have a robust, well-defined capability roadmap in four main areas: distributed targeting, net-centric operations/battlespace management, sensor integration and advanced weapons," says Mathews. The Flightplan covers fiscal years 2008-2014, and will be updated annually. "It is a living document," he says. "We can add, accelerate or eliminate capabilities."
The launching point for the Capability Flightplan is the avionics architecture implemented incrementally since deliveries of the Block II Super Hornet began in 2005 with production Lot 26, and fully realised beginning with Lot 30.
The architecture backbone is a fibre-optic data network and advanced mission computer (AMC). Block II+ uses the latest Type 3 AMC, produced by General Dynamics Information Systems, with two times the throughput and memory of the Type 2 computer in Block II Super Hornets.
Plugged into this architecture are the new APG-79 active electronically scanned array (AESA) radar AAS-46 advanced tactical forward-looking infrared (ATFLIR) pod digital sold-state recorder (DSSR) accurate navigation (ANAV) system and Link 16 multifunctional information distribution system (MIDS).
"Beginning with Lot 30, every aircraft will have AESA," says Mathews. Until then, some F/A-18E/Fs are being delivered with the earlier mechanically scanned APG-73 radar. The US Navy plans to retrofit 135 APG-73-equipped Block II Super Hornets with APG-79, for an eventual total of 415 AESA-equipped aircraft.
The Raytheon AESA brings the capability for simultaneous air-to-air and air-to-ground operation and, starting with Lot 30, two-seat F/A-18Fs will have the advanced crew station, which decouples the front and rear cockpits. "The front-seater can sanitise the airspace while the rear-seater conducts an air-to-ground campaign," says Mathews. Both crew members will have the joint helmet-mounted cueing system.
Lot 30 also introduces the ANAV box, which replaces the F/A-18's CAINS inertial navigator and MAGR GPS receiver with a tightly integrated system that addresses obsolescence and provides "unprecedented air-to-ground accuracy", says Mathews.
Another step in expanding the Super Hornet's precision attack capability has already been taken with fielding of the digital sold-state recorder. Replacing an analogue cockpit video recorder, the DSSR brings the capability to grab and store sensor images, and send them over existing communications links - either Link 16 or the ARC-210 digital radio.
"On ingress, the crew can see ATFLIR streaming video in the cockpit, frame-grab a still image of the target and datalink it to the forward air controller, who looks at the image, annotates it with Blue Force positions and datalinks it back," Mathews says, cutting the time needed to "talk" the aircraft to the target to "low-digit minutes".
With the Lot 30 aircraft as a starting point, the Flightplan lays out a roadmap for expanding the F/A-18E/F's precision-engagement and battle-management capabilities. Much of the focus is on air-to-ground operations, but the Super Hornet is to get an infrared search and track (IRST) sensor to increase air-to-air capability.
Development of the IRST is funded beginning in FY2008, leading to fielding in 2012-13, says Mathews. A targeting, not imaging sensor, the IRST will be integrated with the radar to provide spectral diversity and the ability to engage passively air-to-air. Although it could be mounted internally, a podded sensor is more likely, he says.
Under the Flightplan, the distributed targeting area involves the addition of an image exploitation processor and mass storage unit to allow sensor information such as synthetic-aperture radar (SAR) imagery to be manipulated rapidly. The first increment will build on the AESA and ATFLIR targeting capability by georegistering imagery to an onboard database to generate precise target co-ordinates.
"This will bring precision targeting for weapons on board the aircraft and provide nearly range-independent, pixel-level accuracy in the cockpit," says Mathews. The next step will extend the capability to multiple and moving targets. A mode will be added to the AESA enabling interleaved SAR and ground moving-target indication, allowing the system to georegister moving targets and update their positions.
"Combine that with a weapon datalink and you will be able to release a weapon on the initial co-ordinates and update it in flight as the target moves. We will be able to engage multiple movers, stand off, in all weathers," Mathews says, adding that the final part of the distributed targeting roadmap will add features such as automatic target cueing and aided target recognition to reduce crew workload.
The net-centric operations area of the Flightplan focuses on augmenting the communications links on the aircraft. "More and more they will use the aircraft for non-traditional ISR [intelligence, surveillance and reconnaissance] because of its state-of-the-art sensors, and it needs to communicate with anyone inside or outside the theatre," says Mathews.
Wideband links
Two new links are to be added to the aircraft. A wideband IP (internet protocol) link will provide a "bigger pipe" for streaming video and voice-over-IP using ad hoc networks, compared with the narrowband, pre-established Link 16 networks. The second link will be beyond-line-of-sight satellite communications.
Development of the wideband IP link is scheduled to begin in FY2010, followed in FY2012 by the satcom system. The EA-18G Growler electronic-attack variant of the Super Hornet has receive-only satcom, but the new system will transmit and receive voice and data, says Mathews.
The third area of the Flightplan, multi-sensor integration, will exploit capabilities inherent in the Block II+ Super Hornet by rolling out software upgrades that tie onboard sensors more tightly together and with offboard sensors. As well as the AESA and ATFLIR, onboard systems include the ALR-67(V)3 radar warning receiver, also made by Raytheon, and the BAE Systems ALQ-214 integrated defensive electronic countermeasures system (IDECM).
The ALR-67(V) is a digital cued receiver, and under the Flightplan its capability will be enhanced to allow single-ship geolocation of emitters with enough accuracy to cue the radar for targeting, says Mathews. The capability for multi-ship geolocation using three F/A-18E/Fs, accurate enough for passive targeting, will also be introduced.
Some of most powerful sensor-integration capabilities planned involve the AESA and exploit its ability to act as more than a radar. The first of these is planned to be electronic attack, which will involve using the nose-mounted array of solid-state transmit/receive modules as both a highly sensitive passive emitter locator and enormously powerful directional jammer.
Mathews cautions that the AESA is limited to in-band electronic attack, and in its field of view and field of regard as both a receiver and jammer, but the system promises to be a powerful weapon against other X-band radars in aircraft and missiles. Multi-sensor integration will tie the AESA together with the ALR-67(V) receiver for cueing and the IDECM for jamming techniques generation.
The final area of the Capability Flightplan covers expansion of the weapon types cleared for carriage on the Super Hornet. This begins in FY2008 with Boeing's SLAM-ER stand-off land-attack and Harpoon Block III anti-ship missiles. A later spiral will add the Small Diameter Bomb - probably the seeker-equipped Increment II version designed to attack moving targets, says Mathews.
Although the capabilities outlined in the Flightplan will be developed and fielded over a decade or so, the US Navy plans to upgrade all of its Block II Super Hornets to the Block II+ standard. Block I aircraft will also receive upgrades, but will not be retrofitted to the same standard because they lack the new forward fuselage introduced with Block II and cannot accommodate the APG-79 AESA.
The US Navy, meanwhile, is looking at increasing procurement of F/A-18E/Fs beyond its planned 460 aircraft to offset the delay in Joint Strike Fighter initial operational capability to 2015. The Flightplan is designed to ensure, whatever its generation, that the Super Hornet stays at the leading edge of operational capability.
Where's the beer go?
....And it runs on DIESEL!..........
How does this deal with an enemy who shoots at our forces once per week, then buries his AK-47 again?
AK-47; Automat Kalisnakov, Model 1947. 60 years old and still as effective as any rifle we deploy (using the term effective in the real-world sense, not in a theoretical sense.)
Finally, how does this A/C defeat an enemy that spends nothing on A/C, but anytime it needs a "smart-bomb" and aircraft to "deliver" it simply steals one of our 757 or 767 A/C and crashes it into the WTC, as accurately as any "smart-bomb' we have?
In the crew chief
It can put a hurt on the people who fund the guy who buries his AK-47.
But ... we gotta have the political will to do that.
L
Hmm, finally a true (or near to it) Tomcat replacement....?
The Lightning II won't be ready until 2015?? Is it being bogged down because there are so many NATO nations participating in it's construction/design?
its when they explot the image?
The partner nations are the only thing keeping the F-35 alive. The production costs and unit costs would killl the project if we lost a significant number of partners.
One sticking point is giving out the source code for the flight control system. Britain, a major partner, wants that code for future improvements but LM isn't budging.
It's the irony. We develop weapons that stand off danger in sophiiisticated manner, yet we open borders to human infections, aids and "don't hate" but "lve" pedophiling society. ak47? try a f@g's penis.
If Block II+ would be Ultra Hornet, what would the stealthier Block III be? Super Ultra Hornet Deluxe?
I'm writing a piece on "The Myths of the WOT"
1: It's not a WOT
2: It's a classic guerrilla campaign
3: All the emphasis on "country" ie; Iran, Iraq, Syria is a meaningless Western viewpoint now used by the Wahabist factions to hide their true structure. The countries of SWA are nothing more than 1926 inventions of Lord Balfour. Islamics see themselves as Islamics first, members of their sect second, members of their tribe third, extended family members fourth, and then finally, Iranians, Iraqis, etc.
4: You cannot defeat the UCS (Unconventional soldier) on the battlefield because he gets to chose where, when, how to fight and retire from battlefield when it does not go his way. (reference to Mao's Four Rules)
5: Although you cannot defeat the UCW on the battlefield, the UCW cannot win without extensive logistical, training and political support of 3d party. (The only reason the Colonial UCWs under Washington defeated Cornwallis at Yorktown is that the French fleet was standing offshore, preventing the British fleet from evacuating Cornwallis to NY.)
6: It past, country-sized support organizations were needed to make a guerrilla war possible. Now it's an trans-national quasi-religious movement.
7: We have a choice, use the weapons of OUR choice to defeat the supporters of the WOT, or lose to the UCW in the field.
Correct
Plz see #17.
How does this deal with an enemy who shoots at our forces once per week, then buries his AK-47 again?"
It drops things on him that go "boom!". :-)
Finding that enemy is the hard part, but we have other parts of the combined arms team for that.
"AK-47; Automat Kalisnakov, Model 1947. 60 years old and still as effective as any rifle we deploy (using the term effective in the real-world sense, not in a theoretical sense.)"
Absolutely not. The AK-47 has been pitifully ineffective in Iraq against our body armor. Thank goodness!
"Finally, how does this A/C defeat an enemy that spends nothing on A/C, but anytime it needs a "smart-bomb" and aircraft to "deliver" it simply steals one of our 757 or 767 A/C and crashes it into the WTC, as accurately as any "smart-bomb' we have?"
"anytime"??? I haven't seen any planes crashing into buildings for almost six years...largely due to the efforts of our military including the Super Hornets I might add.
As is usually pointed out on these threads, we need defenses against many different types of enemy, not just one.
At any rate, if you want to see how useful airpower is in the WOT, check out the video below. It should prove enlightening. (BTW the munition involved is a cluster munition, contrary to what the clueless talking head says.)
>>> try a f@g's penis
All in all, I'd rather not.
