It might have been done with earht/rubble in some cases. About revetments made of petrol tanks I cite directly "Hurricanes over Malta" book by Brian Cull et all.

"In a matter of weeks, structures appeared in profusion as land was requisitioned around Luqa, Takali and Hal Far. [...] and 84 large pens built for Wellingtons and Marylands, and more than 200 smaller versions for Hurricanes and FAA aircraft, [...]. Initially the pens were made with sandbags and rubble, a method soon superseded by the use of discarded 4-gallon petrol cans, [...]. These wee filled with earth and limestone rubble, and used to create walls up to 14 feet high. It took 60000 such cans to construct three walls to house a Wellington [...]".

check also some pictures of Takali were you can have hints of revetments here and there

From the few pics availalbe, these were usually square in shape, sometimes with a curved prolongement to cover the open side.

To summarize, my whishlist of MTO revetments is:
- Small V type (stone) - READY by Spudkopf
- Small square type (2 versions: stone or petrol cans or mixed)
- Medium Y type (stone)
- Large C type (internal wall of stone with external earth cover) - WIP by Spudkopf
- Large square (material to be decided)

Having single wall sections would be a plus...

Below I put some pictures of Malta blast pens found on the web

Type 2 (Y shaped Revetment.

I started to draw this based on the post-Husky survey plan, however using the dimensions provided the model was starting to give the Colosseum a run for it's money, not to mention the geometry was coming out all wrong, also if all those drawing are meant to be to the same scale, well then there's something wrong there also.

So plan B.

Using Google maps to roughly measure the length and width of the structure in earlier post (which I rounded to the nearest whole number).





I then cut a screen capture of the same image into Illustrator and proceeded to trace out a vector along the centers of the intact wall, I then thickened this line to ascertain the wall thickness (which I worked to be 800mm).

From this I was then able to build a model in SolidWorks:





I then saved the Solidworks drawing back to Illustrator in 1:100 scale so I could test the fit the revetment with several familiar Axis mediums.



......and all before breakfast.....(well mostly)

- Small square type (2 versions: stone or petrol cans or mixed), some small square shaped revetments, one constructed of rammed earth with a 200l Oil drum lining, and one just of stone are the next cabs of the rank after the C and Y revetments are completed (the square stone version may even be finished before these).

- Medium Y type (stone) see the above post

Given how "thirsty" most aircraft are, I can believe that 4 gallon petrol cans piled up quick. Since they'd otherwise be waste, I could see why they got converted into improvised sandbags.

The only problem is that a texture that uses 4-gallon petrol cans is necessarily limited to RAF and Commonwealth airfields. To simulate USAAF, Free French AF, Regia Aeronautica, and Luftwaffe bases, a "stone", "sandbag", or even "galvanized corrugated sheet," wall texture would be more generic.

In areas other than Malta, my guess is that it would be much more common to use sandbags, and/or stone, which was cheap, abundant, and could easily be moved around with a bulldozer.

My guess is that there is a pre-war RAF engineering manual which provides specifications for "square" ("[-shaped") revetments. Likewise, there's probably are forgotten Italian and German manuals which lays out specifications for Regia Aeronautica and Luftwaffe airfields. The 1941 USAAF Airfield Engineering manual is online. I can provide a link if there's interest.

Many of these objects could be created by retexturing existing objects. In particular, the Large Square revetment already exists. Just give it sandstone, tuffo, "Mediterranean Winter/Spring/Autumn", and "Deep Winter" textures and it's ready to go.

In terms of actual 3D, what's needed is Small V, Small Square, Medium Y, Large C, and Large Square, plus "do it yourself" revetment parts.

nice and fast)

.....did someone say, a square stone revetment?

Using the skills that Sita was so very kind enough to demonstrate, I was able to quickly convert the original V shaped revetment into the square one you see below, the bonus here is that the skinning is more or less done already.

It may seem fast, but I'm still only running at not even a 100th of the speed that you can work, however a key to my apparent speed is my use SolidWorks (SW) to do a lot of the grunt design work before dragging it into the time sucking black hole that is Max, even the above square pen was made easier by creating a model in SW that was then imported into Max, this I could then use as a template to adjust the existing V shaped pen's vertices.

....mmmm could this be a square revetment?





Located at:Aeroporto Boccadifalco (Castelvetrano airfield?), Sicily

Boccadifalco was the old Palermo airport. It is still in use by small aircraft. I have to check the schemes to see if it corresponds. But 5m seems a bit small to me. That one in particular could have be used to house any other equipment like e.g. petrol tanks or motor vehicles...

As a rule of thumb, I would keep the same base aperture of the small V revetment.

Oopps my BAD - been so backwards and forwards with scales this evening, I totally missed that it was only 5.4 metres.

But to belay your fears, I based the dimensions for the model on those from the diagram so it is slightly narrower and shorter than the V type, but due to having parallel walls it can afford to be, see below:



But if you want it bigger let me know!
