Phantom FG Mk.1 - Inboard Pylon Weight Limits

[Richard E]

Although they would probably contribute to a rather sluggish performance, would the FAA's Phantom FG Mk.1's inboard pylons be rated to carry a 2,000 lb payload?

 

I have an idea for an Airfix Phantom finished in a "WHIF" scheme carrying a pair of GBU-24 2,000 pound Paveway Laser Guided Bombs on its inboard pylons........

An F-4 would carry 3 x 500 lb bombs on a TER plus 2 Sidewinders on the inboard pylon, so weightwise...yes.

According to Mr Chant's "Encyclopaedia of Modern Aircraft armament" they were rated to 3,500lbs. That said, I have noticed the odd error in the book so you may wanna take that with a pinch of salt. Then again, it is a Whif... 😉

I know your plan is a WHIF, so this is a bit subjective.

The British Phantoms used the US Navy type pylons. They were just lumps of metal with no internal ERU to load stores onto (that design was for the USAF Phantoms).

 

To load any store a MWA (multiple weapons adapter) had to be bolted to the pylon. Then a CBTE (carrier bomb triple ejector) was fitted.

Finally the required bomb(s) or rocket pods were loaded to the CBTE.

 

 

This would make the 2,000lb Paveways a bit low to the ground.

 

WHIF though, so ..........meh!

Hi, Phne Phixer,

 

I have read that the "Navy pylon" was specifically designed to carry a Sparrow and that it could carry it straight, without any adaptor, launcher or rail added (which would be needed to carry anything else), but that would contradict your information.

I don't know if this helps at all?

Gentlemen

 

Thank you, some very useful information - all I need now is some ability and time.

 

@Phone Phixer as part of the aircraft's proposed upgrade programme I'll simply "WHIF" updated pylons with built in weapons adaptors.

Hi Fernando.

Yes, I have read of the ability for Aim 7 Sparrows to be fitted directly on the navy pylons. They were rail launched rather than ejection launched.

British Phantoms never used this though, it was not a recognised load. Sparrows and the later Skyflash were only loaded onto the 4 Aero 7a launchers recessed in the fuselage underside.

 

In the air defence fit, inboard pylons had the Aim 9 Sidewinders loaded onto the Lau 7a launchers bolted to the side. No ground attack weapons could be loaded without the sequence I put in my above post.

They vould always have adapted USAF pylons I guess!

[iainpeden]

If it's A WHIF you can, within reason, do what you like. Which explains the wingtip mounted sparrows I have on my USAF EE Lightning F.6.

[Silverkite]

two rocket pods and a Sidewinder would be possible for RN Phantoms?

Perhaps of interest?

Great film

Loved it. Great film and a really interesting look at that era of technology.

 

I just remember using TRACOR in the early days of my career, before GPS became a standard fit.
