Scottish Aviation Twin Pioneer

Hello! and Welcome to my suggestion for the Scottish Aviation Twin Pioneer, one of the lesser known transport aircraft of the RAF from the mid 20th century, I feel this could come to game as a unique bomber/ Strike aircraft and as the Title suggests, an air to ground missile carrier…



The Twin Pioneer (often abbreviated to ‘Twin Pin’) is a STOL transport aircraft from the late 1950s, and at first glance it is fairly unremarkable, Low speed, 2 engines, 1.5 Tonnes of cargo, nothing really unique or interesting, and if you read slightly more in the wikipedia you may notice its bomb load on the very last line, however there is far more to this aircraft than first meets the eye.

First However let’s add some backstory, The Twin Pioneer was built and designed by Scottish Aviation Limited at Prestwick airport, Glasgow and was developed from their earlier Scottish Aviation Pioneer from the Late 40s, both aircraft had been designed to be capable of operating from extremely short stretches of land (as short as 300m) and carrying a fair amount of cargo, the twin Pioneer was an overall improvement over its predecessor and was designed with Military roles in mind.

The first orders came from the RAF who ordered 39 Aircraft in 1958, these aircraft saw extensive use in the Malayan emergency in which the Pioneers were used in moving troops and supplies, and on occasion was employed in combat, however these were not standard and were often last minute decisions due to some sort of emergency (having no other aircraft available to stop an enemy advance for example).

Where the Twin Pioneers Truly excelled though, was in the Middle east, where they were deployed to Oman, Bahrain and other areas around Aden and the Persian Gulf. This is where things get interesting, as whilst there had already been minor attempts of arming the Pioneers with Brens being fitted to rear doors or Brownings being fitted under the Gear, the most powerful addition was approved for modification. A French team from Sud aviation experimentally fitted SS.10 and SS.11 Missiles to the Underside of the wings of the Twin pioneer, initially they were not cleared for firing however during an emergency the ‘Twin Pin’ was called upon.

During the Radfan Campaign in Yemen rebel solders had taken cover in a series of cave networks in a Valley, with Hunters launching rocket attacks on them, however the Hunters were too fast to get down into the Valley to accurately take out the Rebels, and thus a Twin Pioneer from Khormaksar was loaded up with four SS.11s and took off to engage the rebels, the slower speed of the Twin Pioneer allowed it to descend right down into the Valley where it fired two SS.11s at rebel positions, destroying them returning to base with two missiles left to spare.

This instance also happens to have been the First case of the Royal Air force ever firing a Guided weapon in anger, around 20 years earlier than when the Royal Navy is credited with during the Falklands War. Aside from this, SS.11 Trials were undertaken by the ETPS back in britain, where so far the only picture of a Twin Pioneer equipped with Missiles comes from (see images).

Outside of the RAF service, the Twin Pioneer was used by several air forces, such as Malaysia, of Whom the Twin Pioneer was the First aircraft to ever be used by their are force. slightly lesser known as well is that a Twin Pioneer was also covertly operated by the CIA under the Guise of the Philippines Air Lines and other cover airlines before being irreparably damaged in a thunderstorm in 1968.

Place in game


Personally I feel this would be an incredibly interesting addition to the British Tech Tree in game and would be a unique and capable ground attack aircraft to fill out the Mid ranks of the Tree, I feel this would work well at around 6.7/7.0 as despite it having 4 capable ATGMs and 2 1000 lb bombs it is very slow and a rather large target so can be picked of easily by enemy fighters or SPAA.

This aircraft would also serve as a testament to the rather unknown Aviation industry in Scotland and given that this is one of the Most capable military aircraft to come out of it I feel it is worth being added to the game, possibly alongside the Bulldog as well.

Cool! Would be interesting addition! Think it would fit around 6.7-7.0

So is there a targeting camera for the SS.11’s or should we expect to see just a view from the co-pilots seat?

Not sure as there is very little info other than the ETPS picture and a couple of first hand accounts, however judging by the pics it seems there was no targeting camera installed. The aircraft is capable of firing them on its own as i have seen several different sources reffering to the canyon attack but im not sure how due to the lack of pics or official documents reffering to them

In game they would probably be hand controlled like Bullpups and AS.20s

COIN/light attack aircraft, my beloved. I adore this! +1

I have one phrase “Scotland forever” we need Scottish tech.

unfortunately there are only 2 scottish vehicles we could get in game (if you don’t count all the Ships built in Glasgow, Rosyth etc) This and the Scottish aviation bulldog as the rest never carried armament of any kind or were civilian aircraft.

I think we’ve had Scotland in game since at least 2012.

Not sure this kind of aircraft would fit into the regular air tree but given its low top speed and relatively modern armament I think this sort of plane would work great in the helicopter tree. Either way, very cool aircraft and it would be great to see some Scottish representation
