Some are easily taken in by appearances

Huh?

"Given Congress' unwillingness to pursue additional revenue, the current Defense Department budget cannot be sustained. Cuts will be necessary, but the F-35B is the wrong place to look. The F-35B provides a virtually unique capability for transforming amphibious assault ships into light strike/air superiority aircraft carriers. In export and international production, the F-35B can similarly transform warships such as the Japanese Hyuga-class Helicopter-Carrying Destroyer into light carriers capable of strike and air superiority missions. The F-35B is a force multiplier in the literal sense: It turns amphibious warships with limited strike capabilities into aircraft carriers roughly as capable as their most formidable foreign counterparts. ..."


Not quite. Some are easily taken in by appearances. The F-35 cannot maintain "air superiority" vs. emerging threats. So that is out. Since it is an other-than-high-threat jet even if it works (whenever the mission systems show up as working) ... well, Marines (or anyone else) can get fire support any other way better/cheaper.

Hype, won't give America true combat capability.

OK, well how about that austre basing thing? 7 tons of gas per sortie? And look at real operational history of how we fight.

In every major conflict involving US ground troops since Operation DESERT STORM, the USMC Harriers have not been unique in their ability to “move forward” and operate “close to the fight”. For example, during DESERT STORM “Hornets based at Shaik Isa utilized the airfield at Jabayl as a FARP [Forward Arming Refueling Point], just as the Harriers did at Tanajib, thus reducing transit time to and from the target area”.
Furthermore, USAF “F16s…generated a tremendous number of sorties while operating from a forward operating location (FOL) at King Khalid Military City (KKMC) in Saudi Arabia, located just 60 miles from the Iraqi border”.

“F-16s operating there were able to exchange their drop-tanks for extra ordnance: KKMC-based missions carried four Mk-84 2,000-pound bombs (double the normal load of two). FOL operations allowed the wing to fly more sorties per day; KKMC missions launched from the…main base in Abu Dhabi to bomb the KTO [Kuwait theater of operations]; landed and rearmed at KKMC for a second sortie to the KTO (which did not require refueling); landed and rearmed at KKMC for a third mission and after attacking the KTO, air refueled to return to Abu Dhabi.”

Like the USMC Harrier, the USAF F-16’s took advantage of a FOL, but the “F-16 carried a larger payload than either the Harrier or the Hornet, and delivered tons of ordnance…with a very small transit and turnaround time”.

Again, nearly ten-years later, during Operation ENDURING FREEDOM (OEF), the USMC Harriers were not alone in their ability to move forward and operate “close to the fight”. In October 2002, a six-airplane detachment of Harriers from Marine Attack Squadron (VMA)-513 set up shop at Bagram, near Kabul, where A-10s had been operating since March of that year.

Later during Operation IRAQI FREEDOM (OIF), Harriers took advantage of a FARP “at An Numaniyah, 60 miles south of Baghdad” but USAF A-10’s also “deployed forward” and operated out of “Tallil Air Base in Iraq”. However, logistics hampered Harrier operations. According to a “Harrier squadron commander…it was a major task keeping such aircraft supplied with jet fuel at that site”. This squadron commander went on to say, “It takes a lot of support and logistics…so we chose to use other platforms”.

Like the Harrier, the F-35B will be a logistics challenge. A number of logistics risks exist with the STOVL variant that do not exist for the other JSF variants, the primary being the vertical lift fan. Although a revolutionary design concept, the reliability and maintainability of the lift fan is still unproven. The lift fan operates on a single shaft that connects to the main engine and spins at a high-rate of speed. According to one study, this lift fan design causes “ added complexity” due to “the need for the clutch to engage and disengage the lift fan”.

Repair of the vertical lift components would very likely call for removing the engine, a traditionally “high repair time task”. Further, the lift fan and swivel nozzle adds to the logistics footprint especially when forward deployed.

According to one study, “While the JSF designers strive to reduce the complexity of the aircraft systems, the fact remains that the STOVL…will by nature be more difficult to maintain than either corresponding CTOL or [Navy] version”. This conclusion centered on “Naval Post Graduate School [studies] which compare projected component designs for the STOVL JSF to current Harrier design and projected [F-35C] design”
