Lower costs to build and maintain, but seems aesthetics and some use complications may have won out.
The X-32 Could Have Been the F-32 (And Replaced the F-35)
...
From four proposals, two airframes were chosen for flight testing and pitted against each other. The winner would earn the lucrative JSF contract. The first is well remembered as the program’s winner,
Lockheed’s X-35, which has since been developed into the preeminent fifth-generation fighter, the
F-35 Lightning II. The second, the “also-ran”
Boeing X-32, has mostly faded into obscurity and is remembered above all for the jet’s ungainly appearance.
Boeing’s JSF entry featured a distinctive engine intake – a single gaping, yawning, angular intake that sat just below an unusually truncated nose. The jet’s fuselage, which sat below delta wings, made a bloated, sagging impression. While futuristic looking, the
X-32 was objectively ugly and appeared unathletic.
Of course, appealing aesthetics had not been Boeing’s objective when crafting the X-32. To win the JSF contract, Boeing hoped to appeal to the Department of Defense with low manufacturing and life-cycle costs. Accordingly, Boeing built the X-32 around a large, one-piece carbon fiber delta wing that could be used as the base of multiple X-32 variants. And Boeing included a simple direct-lift thrust vectoring system that could be outfitted conveniently with a thrust vectoring nozzle (on the appropriate variant) in order to meet the USMC’s STOVL requirements. Cheap and simple – an ideology aligned with the JSF itself.
