Since the 1970’s, FSP has performed stealth and camouflage coating projects in its surface treatment plants and at shipyards. FSP has worked globally for the defence equipment industries, where the requirements for surface treatment quality are high.

“For stealth and camouflage coatings, FSP has a professional staff, extensive experience, strong expertise in surface treatment, and the ability to offer secure document management,” says Pentti Virtanen, CEO of FSP Finnish Steel Painting Oy.

According to Virtanen, work security is also promoted by safety assessments, which are carried out to ensure the integrity of each and every FSP employee participating in the project.

Stealth and camouflage coatings are special coatings, with which the products are given operational features in addition to visual properties.

Target becomes invisible to radar

“The goal is to make the target invisible to radars, i.e., make the coated target absorb radar waves. The aim is then to conceal the target from actively operating search and tracking systems, such as radars and echo location devices.”

Thanks to stealth coatings, a target is only detectable as background noise via radar and heat signals. Stealth technology is nowadays applied to all weapon systems, from aeroplanes to ships and tanks. Submarines are coated to make them as difficult to detect by listening and echo location as possible.

Consultation when necessary

“Usually the stealth and camouflage coating specs come from the customer, but if need be, we will consult the customer on the coating selections. We have performed stealth and camouflage coating projects for the defence equipment industry, where the land and naval forces have had a vast variety of coating needs.”

The purpose of camouflage coatings is to conceal the target visually, and make it as difficult to spot from the surroundings as possible. For this reason, for example tanks, personnel carriers and naval vessels are coated with camouflage paints. A camouflage colouring makes the target blend in the surroundings.

Camouflage coatings utilise the reflection of different wavelengths in the flora of a specific country. In other words, camouflage coatings are optimised for e.g. forest conditions or, if necessary, for urban and sea conditions. Camouflage colours can include, among others, matte green or matte beige, according to the customer’s specs.

Camouflage coatings are usually adapted according to the viewing distance. The camouflage patterns on vehicles are relatively large, whereas the patterns on a fighter’s outfit are small, because for them the greatest threat comes from a short distance.
