Electronic warfare has emerged as the new focus of a larger, multiyear $10 billion makeover of the .
Ending a yearlong negotiating process that involved discussions with potential alternative suppliers, Lockheed has selected to deliver a package of upgrades under the Block 4 program to the ASQ-239 electronic warfare/countermeasures subsystem, both companies announced on Aug. 21.
Normally the details pertaining to the F-35 EW suite is seldom disclosed. However some limited information are being reported by AWST.
New upgrade preceded by recent technology insertion
BAE has now inserted the DTIP system into the ASQ-239 to upgrade Racks 2A and 2B. The acronym DTIP is a combination of two other acronyms: DCRTG, for the Digital Channelized Receiver/Techniques Generator, and TIP, for the Tuner Insertion Program. The combination results in a centralized electronic warfare processor that is more powerful, yet smaller. As a result, the DTIP will allow Lockheed to commission BAE to deliver new capabilities under Block 4.
Block 4 could expand frequency band coverage, add cognitive capability
The list included activating Band 5 receivers for the electronic support measures systems, as well as augmenting the F-35’s existing receivers in Bands 2, 3 and 4. Lockheed has previously said that the ASQ-239 included growth provisions in the existing apertures and aperture electronics to host a Band 5 radar warning capability. The upgrade would require incorporating a Band 5 switch in the new DTIP system.
Block 4 could introduce new software into the ASQ-239 that would enable a “cognitive” electronic warfare capability. Such technology generally refers to an improvement on technique generators based on digital radio frequency memory (DRFM) technology, which identify the chain of signals created by frequency-hopping emitters and develop a matching jamming signal based on stored information. By contrast, a cognitive system uses artificial intelligence algorithms, which learn the signals of advanced emitters that have not been previously recorded and develop a counter technique in real time.
