PARIS --- The service introduction of Watchkeeper, the tactical UAV that has been in development for the British Army since 2005, may be further delayed due to unidentified technical issues that appear to have grounded the aircraft for three months in late 2013.
The Watchkeeper program apparently logged no flight activity between mid-September and mid-January, according to data provided by Thales, the program’s main contractor, which showed that the number of total flight hours and total sorties barely changed between Sept. 16, 2013 and Jan 12, 2014.
As of Sept. 16, Watchkeeper had flown “almost 600 sorties, for a total of about 1,000 flight hours,” a Thales spokesperson told Defense-Aerospace.com in an e-mail follow-up to an interview at the DSEi show in London.
On Jan. 20, responding to a follow-up query, the Thales spokesperson said that “Tests are progressing nominally, as planned. We have now passed 600 sorties and are nearing 1,000 flight hours.”
These figures show no flight activity between mid-September and mid-January. Asked to explain this apparent discrepancy, the Thales spokesperson had not responded by our deadline, three days later.
“The delivery of Watchkeeper equipment is on track and trials are continuing with over 550 hours flying having been completed,” the UK Ministry of Defence in a Jan 31 e-mail statement. Note this is about half the flight hour figure provided by Thales.
“…the Release to Service process is taking longer than expected,” the MoD statement continued, adding that “The last flight was last week, so it’s incorrect to say that the assets are still grounded.”
This unannounced grounding may be one reason why the French Ministry of Defense is back-pedaling on earlier promises to consider buying the Watchkeeper, after an inconclusive evaluation between April and July 2013 by the French army. The evaluation included “several dozen flight hours” from Istres, the French air force’s flight test center in south-eastern France, a French MoD spokesman said Jan. 31. The evaluation report has not been completed, and no date has been set, he added.
The final communiqué of today’s Anglo-French summit meeting, for the first time since November 2010, makes no mention of the Watchkeeper, although it was mentioned in passing by French President François Hollande during the summit press conference.
Thales’ figures on Watchkeeper flight activities have also been provided to other news outlets.
A Jan. 16 article by FlightGlobal quotes Nick Miller, Thales UK’s business director for ISTAR and UAV systems, as saying that “Watchkeeper aircraft have now completed more than 600 flights, exceeding a combined 950 flight hours.”
Aviation Week had posted an article the previous day, Jan. 15, in which it reported that “Thales U.K….is continuing flight trials and supports army training” (Emphasis added—Ed.). However, it is difficult to understand how training can take place without an increase in the number of sorties and flight hours.
The above article says “Watchkeeper may début in spring,” echoing a similar story published Sept. 12, 2013 in which Aviation Week said Thales UK “is hopeful that …Watchkeeper…will be certified by the end of the year.” This did not happen.
This same Aviation Week Sept. 12 story said that the Watchkeeper “fleet has flown more than 1,000 hr. over 600 flights” – a higher figure than FlightGlobal reported on Jan. 16, four months later.
The discrepancies in the figures provided to at least three trade publications clearly contradict company statements that Watchkeeper flight operations are “nominal” and “are continuing,” as they show no flight activity has been logged since September.
The obvious conclusion is that flight activities have been curtailed, either by a technical grounding or because of administrative blockages. In either case, Watchkeeper – which is already over three years late -- has clearly hit new obstacles that will further delay its operational clearance by the UK Ministry of Defence’s new Military Aviation Authority (MAA).
Watchkeeper is being developed by UAV Tactical Systems (U-TacS), a joint venture between Israel’s Elbit Systems (51% share) and Thales UK, the British unit of France’s Thales, under a contract awarded in 2005. UAV Engines Ltd, which builds Watchkeeper’s engine in the UK, is a wholly-owned subsidiary of Elbit Systems.
Originally valued at £700 million, the cost has escalated to over £850 million, and service introduction has been delayed by at least three years.
The British Army is due to receive a total of 54 Watchkeeper unmanned aircraft and 15 ground stations. By late 2013, 26 aircraft and 14 ground stations had been delivered, according to published reports.
