The radio frequency (RF) datalink that provides Roketsan's UMTAS (Uzun Menzilli Anti-Tank Füzesi) long-range antitank missile with its lock-on-after-launch (LOAL) capability was developed by Turkish company Aselsan. The RF VBB (RF Veri Bagi Birimi) is a two-way datalink and operates in S-band (2-4 GHz). It has a 3 Mbps downlink speed and 30 kbps uplink speed.

A complete datalink consists of an electronic unit and antenna mounted in the missile, and an electronic unit and antenna mounted in the launcher.

The missile's electronic unit is 145 mm in diameter, 25 mm thick, and weighs less than 500 g. The launcher's electronic unit is of near identical size and weight. Both require a 24-32 V DC power supply.

Different types of antenna have been developed for the missile and launcher by Turkish company Meteksan Savunma. That used in the missile takes the form of a flat strip with a height of 92 mm and a weight of less than 500 g.

Mounted on the front part of the UMTAS launcher, the antenna unit takes the form of a flat panel measuring 140 mm x 135 mm, and 25 mm in thickness. It weighs less than 300 g.

Qualification trials of the RF VBB datalink ended in December 2012, and the hardware is currently in production.

The datalink hardware is designed to cope with temperatures ranging from -35° to 60° C, and to operate at altitudes of up to 15 000 ft.

Developed as the main anti-tank weapon of the new Turkish T-129 ATAK attack helicopter, UMTAS is being promoted on the international market as the TAM-LR (Turkish Anti-tank Missile - Long Range). According to the latest information released by Roketsan, the length of the missile is 1,800 mm, a figure slightly longer then the 1,750 mm previously stated.

So according to these informations after our SOMs HGK family will be used by our F-35s... Hope our other wepons will be used by our F-35s too...
 
Turkey produces first missile fuel of country

The local missile fuel has one of the strongest propulsion powers in the world, and is good for use in the newturbojet engine missiles, the minister has said.
The local missile fuel has one of the strongest propulsion powers in the world, and is good for use in the newturbojet engine missiles, the minister has said.
The Scientific and Technical Research Council of Turkey (TÜBİTAK) has succeeded in producing the first local missile fuel in the country.

“Missile fuel, which is strategically very important, is produced only by a number of developed countries. The seller nations may impose several limitations or set conditions. Therefore, it is of great importance for us to be able to produce it,” said Minister of Science, Industry and Technology Nihat Ergün.

TÜBİTAK has managed to develop many significant projects in the defense industry so far, offering the Turkish Army a national cruise missile, smart bomb, and a laser-guided missile detector, among others. Now the organization has produced missile fuel by using local means.

The missile fuel was developed over two years by the researchers from TÜBİTAK’s National Metrology Institute (UME), and has started to be produced in a mini pilot facility by using the institute’s infrastructural means. The fuel was able to gain an internationally-recognized quality standard.

The local missile fuel has one of the strongest propulsion powers in the world, and is also suitable for use in the newly developed turbojet engine missiles, said Ergün.

“Such products are of real importance for us to reduce the dependency in defense industry abroad,” he noted, adding that they were very expensive.

“More importantly than other facts, we could not supply this product whenever we want. A number of nations sell this product and they may put several limitations and this is very normal. We’ll fortunately be free of such limitations in time,” he said.

The mini facility has the capacity of 10 liters of daily production. TÜBİTAK UME aims to increase this amount up to 100 liters when the planned facility goes online.
