Multispectral camouflage technology, as one of the important concealment methods in modern battlefields, can help ground combat forces resist multidimensional reconnaissance and enhance the survival capability of troops. In recent years, related technologies have received increasing attention from more and more countries. Recently, Pickwick Security Consulting released a report predicting that the global multispectral camouflage system market will grow at a compound annual growth rate of 40% over the next three years. By 2028, the total market value will increase from the current $200 million to $500 million. The development momentum is good. Many spectral camouflage systems combine traditional camouflage color camouflage with new technologies and materials to help ground combat forces avoid detection of electromagnetic spectra such as microwave, infrared, X-ray, and gamma rays. During the Cold War, with the application of new technologies such as infrared detection in the military field, multispectral camouflage technology emerged as a countermeasure. The US military began mass deployment of equipment in this field earlier. In 1981, the US Army issued camouflage uniforms and camouflage nets with new dyes that could reduce electromagnetic signals; In 1997 and 2003, the US military invested approximately $160 million and $240 million respectively to purchase ultra light multispectral camouflage nets; In 2018, an investment of 550 million US dollars was made to order a new generation of multispectral camouflage nets and continue to promote equipment iteration. Swedish companies started early in the field of multispectral camouflage technology. It is reported that the "Barracuda" system produced by Swedish company Saab has been exported to dozens of countries including the United States, France, the United Kingdom, and Germany. In recent years, unmanned aerial vehicles equipped with advanced sensors have been widely used in multiple local conflicts, causing significant damage to traditional ground combat forces such as tanks, armored vehicles, and artillery. This situation directly promotes the accelerated development of multispectral camouflage technology. Large military companies such as BAE Systems in the UK and Rheinmetall in Germany have all invested in research and development in this field. In recent years, with the rapid development of technology, the compatibility between the functions of multispectral camouflage systems and battlefield requirements has been improved. Firstly, it has a wide range of applications. From the perspective of protected objects, multispectral camouflage systems can be used for individual soldiers, weapon equipment platforms, and command posts. Miranda Company in the UK combines materials such as polyester, polyamide, blended fabrics, and knitted fabrics to launch a series of multispectral camouflage products covering individual camouflage clothing, artillery camouflage patches, and command post shielding nets. From the perspective of adapting to the environment, multispectral camouflage systems can be used in both ordinary battlefield environments and specific regional environments. Saab provides multispectral camouflage systems suitable for the Arctic environment and climate change characteristics to the military forces of countries such as Sweden, Norway, Finland, and Canada. The second is to balance multiple fields. Ground units are more easily exposed during maneuvering, and mobile multispectral camouflage systems have become a development focus for military and defense companies in many countries. From 2017 to 2024, Saab installed a mobile "Barracuda" camouflage system on 589 Ajax armored vehicles of the British Army. In January of this year, the Czech Republic spent 536 million kronor (approximately 25.21 million US dollars) to purchase 13 large oil tankers equipped with multispectral camouflage systems. From this, it can be seen that the application scope of multispectral camouflage technology is extending from combat forces to logistical support. The third is to focus on communication skills. Although early multispectral camouflage systems were able to evade electromagnetic spectrum detection, they could hinder the transmission of our own communication signals. The latest developed multispectral camouflage system ensures stealth capability while allowing our own side to ensure battlefield communication through specific radio frequencies without interfering with the use of global positioning systems. Foreign defense experts have analyzed that the rapid growth in the types, quantities, and capabilities of reconnaissance equipment in modern warfare brings both development opportunities and direct challenges to multispectral camouflage technology. On the one hand, the market space for multispectral camouflage systems is expanding. Multiple countries are strengthening the research and development of this technology and increasing the procurement of related equipment. In 2024, France will order 3000 sets of multispectral camouflage systems. In February of this year, Denmark announced the installation of a mobile multispectral camouflage system on the CV90 infantry fighting vehicle. At the same time, multispectral camouflage systems are gradually developing towards modularity, lightweight, and customization, making them more convenient for use and maintenance on the battlefield. On the other hand, multispectral camouflage technology is facing intensified technological competition. With the deepening of research on multispectral camouflage technology in multiple countries, the weaknesses of this technology will be more comprehensively grasped, or the upgrading and improvement of reconnaissance and sensing equipment will be promoted. Especially with the rapid development of artificial intelligence, the continuous enhancement of situational awareness and recognition analysis capabilities of reconnaissance equipment will put significant pressure on multispectral camouflage technology.
