Your JSF Update


Carrier Drop test h/t Graham Warwick
First and Foremost, I think that we need to start with the cost escalation of the F-35, with the unit cost estimates having escalated from $113.6 million to 136.2 million over just the past few weeks, which has triggered an official notification of a Nunn-McCurdy breach to Congress, which means that the price has escalated by more than 50%.

In the interest of fairness, Lockheed-Martin is rejecting the Pentagon numbers, and claiming that they will hit, or at least come closer to the original numbers, based on ……… I'm not entirely sure what, possibly reading chicken entrails.

Meanwhile, on the other side of the pond, both Italy and the Netherlands are making noises about scaling back their purchases/commitment to the program, (paid subscription required)with the Italians demanding a larger workshare, and the Dutch wondering if the entire thing is simply too dam expensive.

Note that the Dutch are supposed to participate in the Initial Operational Test & Evaluation (IOT&E), purchasing 2 aircraft, but they have only contracted for one, and they can sell the aircraft instead of participating in IOT&E.

It all hinges on the upcoming elections.

On the brighter side for the program the first F-35 with a full sensor suite has flown, sort of:
The mission system installed for the initial flight includes the APG-81 active electronically scanned array radar, EW system, integrated CNI, integrated core processor and the pilot's helmet-mounted display. The electro-optical targeting sensor and 360-deg EO distributed aperture system will be added later.
(emphasis mine)

So the most low observable sensor, and the sensor that is supposed to allow the aircraft to compete against more maneuverable aircraft by giving the pilot a 360° field of view around his aircraft are not yet flying.

Finally, we have an analysis showing that the F-16 in 1998 out-ranges the F-35. Basically a 1998 PowerPoint slide for the F-16 gives a 630 NM radius with conformal fuel tanks on a strike mission on a hi-lo-lo-hi profile with the final 50 NM in and out on the deck, as versus a 728 NM radius for the F-35, which only pops below 5000 feet once.

Additionally, the F-16 carries 2 GBU-10 2000 lb bombs + 2 Sidewanders + 2 AMRAAM, while the F-35 carries 2 AMRAAM + 2 GBU-12 500 lb bombs.

If the F-16 is just carrying 2 AMRAAM + 2 GBU-12, and conducts its operations above at 5000 feet or above, it out-ranges the F-35, and that's without considering that the F-16 numbers include the drag of an external jamming pod, and modern F-16s have internal jammers.

Finally, for your viewing pleasure, some the Jim Lerher's News Hour has a segment on the F-35 that appears to cover all the bases.
