En ese laboratorio producirán archivos de datos de misión: la planificación de misión que el piloto carga en el avión con una tarjeta portátil.
RU y Australia operan 15 F-35B y 18 A respectivamente y esperan adquirir hasta 135 y 72.
Está bien, pero por si alguien se emociona: laboratorio conjunto entre dos países y situado en un tercer país que es el "dueño". Es decir, soberanía la justa. Y planificación de misión, no el software central del avión, ni de interfaz, ni de guerra en red... Supongo que RU como único socio de nivel 1 tendrá otros, esto va más por Australia, socia de nivel 3.

Hundreds of F-35s could have the wrong fasteners in “critical areas,” according to the Defense Contract Management Agency [DCMA]. But F-35 builder Lockheed Martin says the problem may not need to be fixed.
“All aircraft produced prior to discovery of this [problem] have titanium fasteners incorrectly installed in locations where the design calls for Inconel,” the F-35 Joint Program Office [JPO] said in an email in response to a query from Air Force Magazine. “Because of this, the engineering safety analysis of the issue has assumed that each critical F-35 joint was assembled with the incorrect fasteners.”
Deliveries of the F-35 were halted briefly in November when the issue was discovered, but the JPO said analysis in January concluded “that no aircraft operating restrictions or inspections are necessary at this time.”
Inconel is an alloy of nickel and chromium. Inconel bolts are specified for uses where greater strength and corrosion resistance are required, while titanium bolts are used in areas where its lightness helps reduce weight. Titanium has a xlower shear strength than Inconel.
The fasteners in this case are “eddie bolts” and are similar in appearance except for the numbers stamped on them. They are not the same, however: The titanium bolts cost about $5 apiece, while the Inconel parts cost about $20 each. A Lockheed spokeswoman said the two parts are “very difficult to distinguish visually.”
The Lockheed spokeswoman said an initial analysis concluded that “titanium has sufficient strength in locations that called for Inconel eddie bolts.” Another Lockheed official said components are built with “twice the strength specified,” but he did not specify whether this was the case with the titanium eddie bolts.

In addition to the F-35 production line at Fort Worth, Texas, the commingling of the two types of bolts was also discovered at the Italian F-35 Final Assembly and Checkout (FACO) facility, but not the one in Japan, the DCMA reported. Deliveries of the F-35 were halted briefly in November when the issue was discovered.
...
According to the DCMA, there are more than 48,000 fasteners of the two types on an F-35 fighter. The Air Force’s F-35As have 848 Inconel bolts out of 48,919 total fasteners, or about 1.7 percent of the total. The Marine Corps’ F-35B model has 877 Inconel fasteners out of 50,603, also 1.7 percent. The Navy’s F-35C carrier-capable model, though, which has to endure the shock of repeated hard landings on an aircraft carrier, and is larger and heavier than the other two variants, has 51,353 fasteners, of which 1,813, or 3.5 percent, are made of Inconel.

Less than a year earlier, it was holes, rather than fasteners that found Lockheed under scrutiny, after USAF maintainers at Hill Air Force Base, Utah, discovered corroded fastener holes on some aircraft. The holes had either been improperly drilled or improperly treated to prevent corrosion.
