The Boeing XP3B-1 (company designation Model 466) was a proposed patrol aircraft, developed by Boeing for use by the United States Navy in the late 1940s.[1] It was planned to be powered by two Allison T40 turboprops driving contra-rotating propellers, and utilized tandem landing gear. The project was cancelled before any aircraft were built.[2] Specifications{{Aircraft specs|ref=Bowers[1] |prime units?=kts |genhide= |crew= |capacity= |length m= |length ft=108 |length in=11 |length note= |span m= |span ft=125 |span in= |span note= |height m= |height ft=32 |height in=10 |height note= |wing area sqm= |wing area sqft=1400 |wing area note= |aspect ratio= |airfoil= |empty weight kg= |empty weight lb=66000 |empty weight note= |gross weight kg= |gross weight lb=127000 |gross weight note= |max takeoff weight kg= |max takeoff weight lb= |max takeoff weight note= |fuel capacity= |more general= |eng1 number=2 |eng1 name=Allison T40-A-2 |eng1 type=turboprops |eng1 kw= |eng1 hp= |eng1 shp=5200 |eng1 note= |power original= |prop blade number=6 |prop name= |prop dia m= |prop dia ft=17 |prop dia in= |prop note= |max speed kmh= |max speed mph=454 |max speed kts= |max speed note= |max speed mach= |cruise speed kmh= |cruise speed mph= |cruise speed kts= |cruise speed note= |stall speed kmh= |stall speed mph= |stall speed kts= |stall speed note= |never exceed speed kmh= |never exceed speed mph= |never exceed speed kts= |never exceed speed note= |minimum control speed kmh= |minimum control speed mph= |minimum control speed kts= |minimum control speed note= |range km= |range miles=5175 |range nmi= |range note= |combat range km= |combat range miles= |combat range nmi= |combat range note= |ferry range km= |ferry range miles= |ferry range nmi= |ferry range note= |endurance= |ceiling m= |ceiling ft= |ceiling note= |g limits= |roll rate= |glide ratio= |climb rate ms= |climb rate ftmin= |climb rate note= |time to altitude= |sink rate ms= |sink rate ftmin= |sink rate note= |lift to drag= |wing loading kg/m2= |wing loading lb/sqft= |wing loading note= |disk loading kg/m2= |disk loading lb/sqft= |disk loading note= |fuel consumption kg/km= |fuel consumption lb/mi= |power/mass= |thrust/weight= |more performance= |armament= |guns= |bombs= |rockets= |missiles= |hardpoints= |hardpoint capacity= |hardpoint rockets= |hardpoint missiles= |hardpoint bombs= |hardpoint other= |avionics= }} References{{commons category|Boeing aircraft}}Citations1. ^1 Bowers 1989, p.568. 2. ^Andrade 1979, p.206.
