A begin of a rework of Da Nang area. River added, port added. I think i made the town a little bit to big. It is more as it is today, but i think during Vietnam War it was smaller. I will try to find an aerial photo of that timeframe and then i will make the changes.

A similar system, but only with different materials.

To come back to the SAM sites and the concrete roads. Swambast is right and wrong at the same time. It is correct to say, that the SAM batteries were semi mobile. The SAM sites were static. The vietnamese built more SAM sites, than they had SAM batteries. They rotated the batteries through the SAM sites per random or, when the site "demask itself" with opening the fire. After the battle was fought, the vietnamese moved the SAM battery to reduce the risk to be attacked by the opponent. Later, so in the mid of Vietnam war, they learned, that the opponent was able to destroy fortified SAM sites and he had the power to do this. From that time a lot of SAM batteries were placed somewhere in the nowhere. They stayed there for a couple of days or till they were fighting a battle. Then they were relocated. Old soldiers rule: "After firing move to a new fire position. If not you will die." The SAM sites itself were built in the dry periode of the year. In this time there was no need to inforce the soil with concrete. A truck or lorry (how our british friend would call it) could easily drive on it. But this changed very fast in rain periode. The truck could not operate under this conditions and so the ways were inforced by concrete. But you should not imagine a 5 or 6 meter wide road made by concrete or tarmac. It was made by a technology, which we call in eastern Germany "Plattenstraße in Form einer Spurbahn". No idea, how you call in the America or the rest of the world. Basically such a road is puzzled together by single plates of concrete. Each plate is 3 meters long, 1 meter wide and 0.25 meters thick. The plate has rectangular holes. It weighs 1 metric ton. To form a road two lines of plates were laid out. The distance between the plates is 1 meter. The room between the plates and outside the plates will be filled with gravel and get finally a layer of soil. The reason is, that on the soil vegetation can grew up. After a while such a road is very difficult to see from a plane at certain distances. Here you see such a road which was made by this technology. It can operate 40 ton trucks under all weather conditions easily. You see the "hole plates", the two lines of plates and you see how the road is vanishing at a certain distance.

I used static airlines in some of my terrains. They are made by JimBib.

I'm not really happy with the SAM site object. It is good for desert areas, but for Vietnam or Europe, i think my SAM site, consisting of individual part can be better adjust to local obstacles, like trees.

So the SAM site will look in the next update of DRV 2.0

This i mean with reworking of target areas. This is one point of many. The number of SAM sites is to low, compared with reality of Vietnam War. It were over 200 sites in 1968/69 and more than 300 in 1973. But in reality not all SAM sites were used by the Vietnamese. They moved their SAM batteries between the SAM sites, so that some sites were empty while others were used. If i could "switch on" the active sites by random ..... That would be a nice feature.

View File DRV 2.1 DRV 2.0 terrain Democratic Republic of Vietnam or better known as North Vietnam ***************************************************************************** ++++++++++++++++++++++++++++++++++++++++++ This terrain is written for SF2NA and SF2E or SF2I or SF2V. +++++++++++++++++++++++++++++++++++++++++ I. Short description: This terrain covers North Vietnam, parts of South Vietnam and Thailand. The timeframe of the terrain is from 1964 to 1979. It is made as a NavalMap so that you can fly carrier missions against North vietnam. You can fly following missions for the American and their allies, the South Vietnamese: SWEEP,CAP,ESCORT,INTERCEPT,STRIKE,SEAD,ANTI_SHIP,RECON,CAS,ARMED_RECON For the North Vietnamese you can fly this missions: CAP,INTERCEPT DRV 2.0 is a rework of DRV 1.4, a terrain which i made 20 years ago. I gave it a new tileset, reworked some tiling and some target areas. Further rework of the target areas is neccessary and will be done later. ++++++++++++++++++++++++++++++++++++++++++++++++ II. INSTALLATION: To run this terrain you need SF2NorthAtlantic and SF2 Israel or SF2 Europe or SF2 Vietnam. Unzip all files into your saved game folder ...ThirdWire\StrikeFighters2XXXX Thats it. If you have SF2Europe installed you must do nothing more. If you miss SF2E and have SF2Israel you must open file DRV.ini with Notepad editor and look for the lines: //CatFile=..\IsraelME\IsraelME.cat CatFile=..\GermanyCE\GermanyCE.cat change the entry into: CatFile=..\IsraelME\IsraelME.cat //CatFile=..\GermanyCE\GermanyCE.cat If you have SF2Vietnam, but no SF2 Europe then open DRV.ini with Notepad editor and look for the lines //CatFile=..\VietnamSEA\VietnamSEA.cat CatFile=..\GermanyCE\GermanyCE.cat change the entry ino: CatFile=..\VietnamSEA\VietnamSEA.cat //CatFile=..\GermanyCE\GermanyCE.cat save the file ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ++++++++++++++++++++++++++++++++++++++++++++++++++ III. Credits. Tileset is basing on Starys Green Hell 3.0 tileset. I converted it to jpg format and merged the 512x512 tiles to 1024x1024 pixel tiles. Tileset green made by Wilches Korat Air Base ArmourDave I hope i have not forgotten someone. . ++++++++++++++++++++++++++++++++++++++++++++++++ IV. This Terrain is Freeware. Commercial use is not allowed. And i say it again for the YAP, YankeeAirPirates file thiefs, the usage of this terrain and/or parts of the terrain for commercial use is not allowed!!!!! +++++++++++++++++++++++++++++++++++++++++++++++++ V.

Hun over the muddy waters of a vietnamese river.

I will include Udorn in a further update. The DRV 2.0 terrain had in major part the target areas of DRV 1.4. I made only some minor changes. I future i will rework the target areas completly. With the mighty tools we have today it is much easier and faster to do than 20 years ago.

Great addon. I will include it in an updated version of DRV 2.0 I have uploaded DRV 2.0 just now. It is a beginning. Further rework of the target areas is neccessary. I will do it in the next time. Give me 2 weeks.

The Hun over North Vietnam. (DRV 2.0 terrain. WIP)

At the moment i'm working on DRV 2.0 terrain. I promised to release a Beta today, but the real life ..... You know. Shit happens. My wife broke our printer and then she said: "Can you repair it?" That's why the delay. I think tomorrow i will release the Beta. WIP screenshot. Thud near Korat AB. BTW is it possible to connect a ground object in the target areas with a random marker? I ask, because the North Vietnamese had over 200 SAM sites in 1968, but only 50 batteries, which were rotating through the SAM sites. With a random value i could simulate such SAM battery movements.

Thud over Korat AB (DRV 2.0 terrain WIP) Can someone remember who made the file of this base?

So DRV 2.0 looks at the moment: Carrier ops are possible now. The target areas need a completly rework. This terrain is 20 years old now. It is still a lot to do, to bring it to a up to date standard. But i think tomorrow i will release a Beta version. Hopefully CA site is not to slow. If so i will try it on monday again.

And touchdown!!

The Su-27 is a 40 years old plane. It was made for Cold War. But today it is only useful in the air defence role. It can't survive in areas, which are covered by modern air defence systems.

Somewhere over Vietnam

Somewhere over North Vietnam.

Coastal tiles are done. Still to do are river in city tiles and railways i farmland tiles. WIP screenshot shows the coastline and sea tiles. If you look to the river you see one of the old river in city tiles.

SitRep: Most of the tiles are now on the new standard. Still to do are the coastal tiles and the city river tiles. I hope i can do this tomorrow. The problem of my very first terrains are "potholes" in the landscape. To cure this will need some time. But i hope i can release a first Beta version of DRV 2.0 terrain on sunday.

Over North Vietnam.

I started a small update of the DRV terrain to bring it on SF2 standard and give it a better tileset. WIP Screenshot shows old and new tiles. The new tiles i have taken from Rio de la Plata terrain. They are basing on Green hell tileset.
