Default [3e] McDonnell F-101 Voodoo

McDonnell F-101 Voodoo (TL7)
In 1946, the USAAF began seeking the development of a long-range turbojet fighter. The initial attempt by McDonnell, the XF-88, proved to be underpowered and too slow, but was further developed into the F-101. First flown in 1954, the F-101 entered service in 1957. Although too late for the Korean War, the F-101 served as a propaganda platform to demonstrate to the Soviets the speed and range of modern USAF fighters. These record-breaking achievements earned the aircraft the nickname of the "One-Oh-Wonder."
Although the interceptor version of the Voodoo saw little actual service, the reconnaissance version (F-101C) was used in the Cuban Missile Crisis and in the Vietnam War. The plane was retired from front line service in 1971, and served in the Air National Guard until 1983.
The F-101B is a two-seat interceptor version. Crew is one pilot and one radar officer. It mounts two Genie nuclear-tipped missiles and two Falcon missiles. These missiles are mounted in opposite sides of a rotating pallet, allowing only two of the missiles to be fired at a time; the pallet then rotates 180 degrees to expose the other pair of missiles. It can also carry two 450-gallon drop tanks to increase range. The Genie missiles or drop tanks can be replaced with Falcon missiles instead. It has a range of 1,550 miles, and burns 1,079 gallons of jet fuel per hour at routine usage. A full tank of fuel costs $6,159. 407 built.

F-101B
Subassemblies: Body +4, High-Agility wings +2, 3 retractable wheels +1.
Powertrain: Two 11,990-lb. thrust turbojets with afterburners, 3,000-kWs lead-acid battery.
Fuel: 2,053 gallons jet fuel in self-sealing standard tanks (Fire 12) [Body]. Can carry an additional 900 gallons in drop tanks.
Occupancy: 2 NCS.
Cargo: None.

Armor
All: 4/20

Weaponry:
4x 20mm autocannons/M39 [Body:F] (375 rounds each).*
*Linked.
2x MB-1 Genie nuclear missiles [Body:U]**
2x AIM-4 Falcon missiles [Body:U].
2x 450-gallon drop tanks [Body:U].**
**May instead carry a Falcon missile, for a total of 6 AIM-4s.

Equipment:
Body: Long range radio with scrambler (300-mile), autopilot, navigation instruments, IFF, targeting radar (10-mile), flight recorder, arrestor hook, refueling probe, two ejection seats, 40,000-lb. vehicular parachute, ½ man-day limited life support, full stabilization for cannons, four hardpoints and internal bomb bay.

Statistics:
Size: 69'x40'x18' Payload: 11.7 tons Lwt.: 26.2 tons
Volume: 725 cf. Maint.: 13 hours Price: $2,378,851

HT: 10. HPs: 1452 Body, 552 each Wing, 132 each Wheel.

aSpeed: 1029 aAccel: 9 aDecel: 19 aMR: 5 aSR: 3
Stall Speed: 173. With afterburner, aSpeed 1221, aAccel 13.
gSpeed: 484 gAccel: 24 gDecel: 10 gMR: 0.25 gSR: 3
Ground Pressure Extremely High. No Off-Road speed.

Design Notes:
Body is 725 cf; wings are 60 cf each, wheels are 36.25 cf. Wing volume was reverse-engineered from actual wing area (368 sf). Structure is Heavy, Standard with Very Good Streamlining. Sealed. Armor is Standard Metal. Mechanical controls. Design loaded weight is 51,788 lbs.; this was increased 1% to the maximum take-off weight. The design afterburner produces 17,985 lbs. of thrust; the real-world value of 16,900 lbs. of thrust was used for performance calculations. The historical unit cost was $1,754,066.
The missiles are mounted on a rotating pallet with only half of the compliment externalized. This was modeled as a bomb bay for the concealed missiles and hardpoints for the exposed ordnance and drop tanks.

Variants:
The F-101A was armed with 4 20mm autocannons and could carry a single 3,721-lb. nuclear weapon. 77 built.
The TF-101B featured dual controls for use as a trainer.
The F-101C was similar to the -A. 47 built. The RF-101C was the reconnaissance version. 166 built.
The F-101D and -E were to feature different engines. They were not built.
The F-101F were 153 -Bs upgraded with IR detection systems and improved fire control systems. The refueling probe was deleted.
The RF-101G and RF-101H were -As and -Cs used by the ANG.
The Royal Canadian Air Force use the F-101 extensively from 1961 to 1985 as the CF-101B (56 aircraft) and CF-101F (10).

I don't think your hardpoint writeup is clear without the color text. Unfortunately, the right format isn't obvious.
  • It seems you want to say 'two Falcons, two Genies, two tanks, and the Genies or tanks can be swapped for Falcons'. That would be 0-2/2-6/0-2, not 2/4-6/2 (which totals 8-10).
  • The original Vehicles format lists hardpoints separate from weaponry, as surface features, since in theory they can carry anything from bombs to booster rockets (compare VE142).
  • The revised Lite format lists them as Equipment, External (on body).
  • WWII muddles the waters by listing them the way you did, but W:MP comes close to the Lite standard by making them Equipment in the respective subassembly.
  • Either way, you shouldn't list the missiles as weaponry and the hardpoints, since then readers could believe that there is hardpoint capacity in addition to the missiles.
Apart from the writeup questions, have you considered to simulate the missile bay as a revolver missile launcher?

That is correctly what was intended, but I do see now that it is potentially confusing.

And since I began my vehicle building career there, I guess I gravitate towards that format.

Point taken.

That would probably be a better way to handle it. The "bomb bay" is really only added space to allow the missiles to be rotated into the fuselage. They certainly cannot be fired from there, so it is not a true bomb bay.

Taking the lower end of each range, that is 2+4+2 = 8 items.
