This is a set of 6 IR cameras placed around the aircraft, and the F-35 is the only US aircraft with a full DAS system..
But not ship - and it is available for integration on other platforms.
Mind you, not sure that " DAS is working on the F-35 aircraft that the USAF/USMC/USN are flying." adequately explains the current situation. Permit m to quote from the
DOT&E FY2013 Annual Report on the F35...
.....October reports for the latest Block 2B mission systems software increment in flight test show a rate of 11.4 hours between anomalies, based on 79.5 hours of flight test. Subsystems, such as the radar, EOTS, DAS, and the navigation solution often require component resets as well, but these are not tracked in the stability metric.
...........Initial results with the new increment of Block 2B software indicate deficiencies still exist in fusion, radar, electronic warfare, navigation, EOTS, Distributed Aperture System (DAS), Helmet‑Mounted Display System (HMDS), and datalink. These deficiencies block the ability of the test team to complete baseline Block 2B test points, including weapons integration.
.............Projections for completing Block 2B fight testing using the historical rate of continued growth ... show that Block 2B developmental testing will complete about 13 months later, in November 2015, and delay the associated fleet release to July of 2016.
- The EOTS fails to meet target recognition ranges, exhibits track instability in portions of its field-of-view, and has large line-of-sight angle and azimuth errors when computing target locations. These deficiencies are being investigated and addressed by the program with software fixes.
......- Latency with the DAS projection has improved from earlier versions of software, but has not yet been tested in operationally representative scenarios.
.....- The DAS has displayed a high false alarm rate for missile detections during ownship and formation flare testing. The inability of the DAS to distinguish between flares and threat missiles makes the warning system ineffective and reduces pilot situational awareness.......
