BAE to Provide Joint Strike Fighter Transmitter Countermeasures
April 4, 2014

BAE Systems Electronic Solutions, Nashua, N.H., is being awarded a $47,352,248 indefinite-delivery/indefinite-quantity delivery order contract for the manufacture of the transmitter countermeasures T-1687A/ALE-70 (V) in support of the Joint Strike Fighter program. The Naval Supply Systems Command Weapon Systems Support, Mechanicsburg, Pa., is the contracting activity (N00104-14-D-K054).

.....QUESTION!!!!...

is the ALE-70 installed on the F-35??

note* a lot of "blather" rambling around about an Aussie purchase but simply could be for their F-18s. I admit I am not familiar with this specific device, thus the question to those more knowledgeable.

Australia is buying 1952 ALE-70s which seem a lot. Can we infer anything from the qty ordered?

Yes, in the Spaz reference (an apples and oranges thread of decoying and jamming) the ALE-70 has a 400 hour life limit per a document provided by Spud.

In more simple terms the ALE-70 is an expendable towed RF decoy for spoofing attacking radar controlled missiles. Speculating that there maybe four(ish) ALE-70 per a/c. Similar to the ALE-50 on B-1B and F/A-18E/Fs.

Does the aircraft have the ability to reel in an ALE-70 that has been deployed?

I would say, YES.

For example the ALE-55 does have a reel in option, which can be read on the ALE-55 brochure which can be downloaded from the page below:
http://www.baesystems.com/en-us/product ... owed-decoy
(AN/ALE-55 brochure link)

In the brochure the following can be read:

Reel out/Reel in option
In addition to the standard “fast deploy expendable” decoy,
BAE Systems has flight tested a “Reel out/Reel in” deployment system
for fighter aircraft. Based on a flight-test-proven design for C-130
aircraft, this option replaces expendable decoys with decoys that can
be used again and again. This not only means the decoy will be there
when it’s needed, but it also lowers the system’s life-cycle costs.


So if the ALE-55 has a reel in option than I cannot see why the ALE-70 shouldn't have the same mode as well :wink:

Thanks ricnunes, though I'm still curious how they manage it without dinging the fuselage . . I still puzzle at the size of the Oz order though. Matbe a Black Friday sale? :mrgreen:

Yes, a bit difference in a ding in a Herc vs. a ding in a Litenen (yes, expendable). Divide the purchase number by the a/c number and the balance would yield the number of flights per 400 hours operating and....the number per each a/c 4(ish)??
:roll:

Well, if you read the ALE-55 brochure or the quote from the brochure that I posted above:

Reel out/Reel in option
In addition to the standard “fast deploy expendable” decoy,
BAE Systems has flight tested a “Reel out/Reel in” deployment system
for fighter aircraft.
Based on a flight-test-proven design for C-130
aircraft, this option replaces expendable decoys with decoys that can
be used again and again. This not only means the decoy will be there
when it’s needed, but it also lowers the system’s life-cycle costs.


Note the part in bold and underlined :wink:
Well there's a "reel in" system for fighter aircraft, this for the ALE-55.
So again, I don't see why the ALE-70 couldn't have such a system. But yeah, a better clarification on the subject would be great.

This not much but it somehow adds some details about the ALE-70 Australia deal with a little bit more info on the ALE-70:

http://www.airforce-technology.com/news ... a-5893336/


Designed and produced by BAE Systems for deployment from the F-35 aircraft, the ALE-70 towed radio frequency countermeasure consists of the reel/launcher assembly, tow line, T-1687 countermeasure transmitter, and electronic and mechanical sub-assemblies.

Correct.


Attachment points for four dispensers can be seen.

OK thanks ric and spud... much clearer now how ALE-70 is to be operated from the jet.

Navy asks BAE Systems to build T-1687/ALE-70(V) electronic warfare (EW) towed decoys for F-35
August 17, 2018 By John Keller Editor

MECHANICSBURG, Pa. – Airborne electronic warfare (EW) experts at BAE Systems will provide the U.S. Navy with fiber optic towed decoys to help defend the F-35 joint strike fighter aircraft from air-to-air missiles and other incoming threats.
Officials of the Naval Supply Systems Command Weapon Systems Support activity in Mechanicsburg, Pa., announced a $70.4 million order Thursday to the BAE Systems Electronic Systems segment in Nashua, N.H., to build the T-1687/ALE-70(V) countermeasures system for the F-35.
Designed and produced by BAE Systems for deployment from the F-35, the ALE-70 towed radio frequency countermeasure consists of the reel and launcher assembly, tow line, T-1687 countermeasure transmitter, and electronic and mechanical subassemblies. It also has canisters, and explosive cartridges to deploy the decoys.
When deployed from the aircraft, the ALE-70’s countermeasure transmitter responds to commands from the countermeasure controller located in the jet and emits waveforms to confuse or decoy adversary radars or radar-guided weapons. The system may be towed or free-flying.

The Navy is making the order to BAE Systems sole-source because the company is the sole designer, developer, and producer of T-1687/ALE-70(V) countermeasure transmitters, and is the only responsible source with the technical data and requisite knowledge to meet Navy requirements.
The T-1687/ALE-70(V) countermeasures system functions similarly to the AN/ALE-55 fiber optic towed decoys (FOTDs) aboard the Navy's F/A-18E/F Super Hornet jet fighter-bomber fleet, although the ALE-70 is specially designed and fitted to the F-35.
The AN/ALE-55 transmits complex electronic countermeasures signals from a transmitter that trails behind its combat jet to spoof incoming radar-guided anti-aircraft missiles.

The aircraft-towed decoy with onboard electronics works together with the Super Hornet's electronic warfare system to jam radar seekers in air-to-air missiles. The system also can lure incoming missiles away from their actual targets.
The ALE-55 detects a threat radar in its acquisition mode and uses radar jamming to prevent it from locking to a target. The ALE-55's electronic warfare package analyzes the threat, and the towed decoy emits the jamming signals to confuse the incoming missile's tracking radar. If an incoming missile locks on with radar, the ALE-55 analyzes the signal to determine the best jamming technique to break radar lock.
The ALE-55 system consists of an onboard electronic frequency converter (EFC) and a fiber-optic towed decoy. The EFC converts radio frequency signals sent from the plane’s electronic warfare system into data coded and transmitted via light to the fiber optic towed decoy.
On this T-1687/ALE-70(V) order BAE Systems will do the work in Nashua, N.H., and should be finished by March 2021.
