Tactical Headgear for Operational Requirements (THOR) has been adopted by the Finnish Defense Forces as the helmet component of their Soldier Modernization Program: Warrior 2020. A multi-year contract was recently let by the Finnish Defense Forces Logistics Command, with initial deliveries being used for acceptance testing. Savox is the prime contractor of the consortium behind THOR, along with industry partners, Millog Oy (night vision) and Fy-Composites Oy (ballistic protection).
The core of THOR is a boltless design ballistic helmet made from a Dyneema/Aramid blend providing protection against ballistic threats: fragments and bullets to STANAG 2920 1.1g FSP-v50: 450. 750m/s – back face deformation <25mm; NIJ0106.01 9 mm FMJ bullet 430m/s. The shell also meets EN 397 shock absorption requirements.
Additionally, special night vision goggles and hearing protection have been designed specifically to integrate with this helmet. As you can see in the photos, the NVGs stow very close to the helmet and are light enough to not need a counterweight. The goggles offer a 60°-wide view angle (also available is 40° FOV) and can be used in mono or bino configurations. These us Millog’s Hi60 3rd Gen tubes offering human recognition up to 150-250m as well as an integrated IR illuminator.
The various technologies developed specifically for the helmet are marketed under FLEXfamily.
For example, the FLEXfit ratchet system allows the rapid adjustment of fit for a wide variety of head types. Next comes FLEXadjust which covers the adjustable, multi-axis mounting systems for the NVGs and earpro. In addition to ANR headphones (23dB), the user can attach a boom or bone conductive skull microphone in addition to throat and internal respirator mic options. Like most systems currently fielded, power and volume adjustments are on the side via buttons. Additionally, the earphones can be placed in one of three positions without removing the helmet or losing communications.
FLEXnet is an integrated databus both internal and external to the helmet. This works hand-in-hand with the FLEXrail which allows the mounting of Picatinny compatible accessories to the powered rail system incorporating a USB integration interface. THOR features five of these FLEXrails which can bring data into the from cameras and sensors helmet as well as exfil it to other devices such as radios. These FLEXrails also incorporate FLEXpower which provides power to the devices as well as all accessories internally through the helmet.
