From F-35 News thread:
Note emphasis on real issue as opposed to alarmist headline!
This is not a case of the EW system being obsolete against its spec or the threats it will face but rather simply a case of parts becoming harder to source. The same issue hit the F-22 (to a far greater extent) and is a characteristic of other similar programs as well.

The United States has embarked on a technology refresh development track for the electronic warfare (EW) module of the F-35 Lightning II Joint Strike Fighter to overcome obsolescence issues before the system has even made it into service.
This has seen the US Naval Air Systems Command place a USD149 million contract to Lockheed Martin, as a modification to a previous advanced acquisition deal and covers the "redesign and qualification of replacement F-35 Lightning II Joint Strike Fighter Electronic Warfare system components due to current diminishing manufacturing sources".
Principal components of the fifth-generation multi-mission F-35's integrated avionics suite are the Northrop Grumman AN/APG-81 Active Electronically Scanned Array (AESA) radar, Northrop Grumman's AN/AAQ-37 Distributed Aperture System (DAS), the Lockheed Martin AAQ-40 Electro-Optical Targeting System (EOTS), a VSI (joint venture between Elbit Systems and Rockwell Collins) Helmet-Mounted Display System (HMDS), and BAE Systems' digital AN/ASQ-239 (Barracuda) system derived from the F-22 Raptor's AN/ALR-94 EW suite.
