Rafale, Typhoon, F-22, F-35, and J-20, why are most fighter jets painted in grey color? The answer will surprise you
The grey color isn't just about looks, it is part of the strategy. Grey helps the jet blend into both the sky and the ground, making it harder to spot with the naked eye.
Jets like the F-5 Tiger II use two or three shades of grey to better match different backgrounds. In war, this kind of visual camouflage is the first line of defense against being seen and targeted. How paint helps fighter jets avoid heat-tracking missiles
The hotter a fighter jet gets, the easier it is to spot using thermal cameras or heat-seeking missiles. That's why new types of paint, like low-emissivity topcoats, are now being used. These special coatings help keep the surface of the jet cooler, which lowers its thermal signature, making it harder for enemy infrared sensors to detect. Lighter paint saves fuel and boosts speed
In 2025, UK's EasyJet airline used a new lightweight paint that made each airplane about 27 kg lighter. This small change could save up to 1,200 tons of fuel across their entire fleet every year.
In fighter jets, though, lightweight paint is not just for saving fuel, it's used to improve performance. A lighter jet faces less air resistance (or drag), so it can fly faster, farther, and with better agility during missions. Outsmarting modern sensors
Today's enemy technology goes far beyond radar. It also includes infrared, ultraviolet, and even multi-spectral sensors that can detect heat, light, and more.
To stay hidden, modern fighter jets are now using anti-thermal and multi-spectral coatings. These advanced paints reflect light and heat in special ways to confuse different types of sensors, which helps the jet remain unseen from all angles. Fighter jets follow strict painting rules
Every air force in the world has its own painting rules for fighter jets. It's not just about choosing a color, jets must also have safety markings, maintenance codes, and warning signs painted in the right places.
If a jet doesn't follow these military painting standards, it might not be allowed to fly. In some cases, the jet can even be grounded or suspended until it meets the rules. Why most fighter jets are painted grey
The grey color you see on fighter jets isn't just for style, it's carefully chosen for many smart reasons: It reflects sunlight evenly, so the jet doesn't get too hot.
It's less visible to the human eye, making it harder to spot in the sky.
It helps reduce visibility on radar systems too.

Japan-US trade agreement: Tokyo to import ‘very beautiful' Ford F-150s; duties on Japanese car exports still unclear
Japan is set to begin importing Ford's hefty F-150 pickup trucks, US President Donald Trump said on Tuesday, even as questions linger over the full scope of the countries' trade agreement. The move comes as part of a deal announced in July, under which Japanese imports will be hit with a 15% "reciprocal" tariff, lower than the 25% previously threatened. The new rate is due to take effect from Thursday, in line with changes affecting several other countries. In exchange, Tokyo has agreed to lift "restrictions" on American cars entering Japan, including a key concession to recognise US vehicle safety standards. 'They're taking our cars,' Trump told CNBC in a phone interview. 'They're taking the very beautiful Ford F-150, which does very well. And I'm sure we'll do very well there, and other things that do very well here will also do well there.' While Japanese carmakers export millions of vehicles to the US each year, American cars are a rare sight on Japanese roads. Ford pulled out of the Japanese market nearly ten years ago, citing weak sales, as reported by AFP. The F-150, which is 2.4 metres (96 inches) wide with mirrors, is considered too large for Japan's narrow roads, and American models often come with steering wheels on the left-hand side, opposite to Japanese driving norms. Despite the headline agreement, several aspects of the trade deal remain unclear. A major sticking point is when the US will reduce its own tariffs on Japanese cars. Currently, these stand at 27.5%, made up of a long-standing 2.5% levy plus an additional 25% introduced under Trump. That figure is meant to drop to 15%, though a timeline has yet to be confirmed. There is also uncertainity on whether other levies on Japan will be capped at 15%, or if this would come on top of existing ones. A recent US executive order suggested that the upper limit would apply solely to the European Union, not Japan. On Tuesday, Japan's tariffs envoy Ryosei Akazawa departed for Washington on what marks his ninth trip in ongoing trade talks. 'One purpose of my visit is to prompt the issuance of the president's executive order regarding tariffs on autos and auto parts as early as possible,' Akazawa said before leaving. 'I have confirmed with the United States that there are no discrepancies (regarding the reciprocal tariff rates), but keeping in mind the new duties will be implemented on Thursday, I would like to provide a reminder for a thorough response beforehand,' local media quoted him as saying. Adding to the confusion, Trump claimed that Japan would be investing $550 billion into the US economy, with America retaining 90% of the profits. 'That's like a signing bonus that a baseball player would get,' he told CNBC. 'That's our money. It's our money to invest as we like.' However, Japanese officials have indicated the sum will mainly comprise loans and loan guarantees, rather than direct investment.

This Muslim country, India's friend, to purchase Turkey's 5th gen Kaan fighter jet, name is...; Erdogan threatening US dominance due to...
Turkey's Kaan fighter jet (File) In a major threat to the United States' dominance in the global arms market, Turkey, already considered a drone manufacturing powerhouse, is now posing a challenge to US-made stealth fighter jets, including the F-35 Lightning II, with its indigenous Kaan fighter jet, which is being viewed by many countries as a pocket-friendly, and more accessible to US fighter planes, that come loaded with preconditions, apart from the hefty price tag. According to media reports, Indonesia, the world's largest Muslim country, recently signed a deal with Turkey, to acquire a fleet of 48 Kaan fighter jets, while Egypt has also expressed interest in acquiring the Turkish-made 5th-gen stealth fighter. Experts believe that this poses a direct challenge to the US in the fighter jet market, which is dominated by Washington, its European allies, along with Russia and China. How powerful is Turkey's Kaan fighter jet? Developed by Turkey's state-owned Turkish Aerospace Industries (TAI) to replace the country's aging fleet of F-16 fighter jets, the TAI Kaan, commonly known as the Kaan, is a 5th-generation, twin engine stealth fighter jet designed for all-weather air superiority. Ankara is presenting the Kaan fighter as a cheaper, more accessible option to the US' F-35 stealth fighter, to entice smaller nations, especially Gulf countries, to purchase the aircraft. Recently, Turkish President Recep Tayyip Erdogan announced that Indonesia and Ankara have signed an agreement for the former to purchase 48 Kaan fighter jets, while reports have emerged that Egypt has also expressed interest in the stealth fighter. Why is the US concerned? According to geopolitical experts, the US has not offered the F-35– its most advanced fighter aircraft– to Israel's neighbours in the Middle East as it wants the Jewish nation to retain its technological edge and aerial superiority in the region. Last month, Turkey signed a preliminary deal with Britain and Germany to acquire a fleet of 40 Eurofighter Typhoon fighter jets, triggering alarm bells amongst Ankara's rivals in the Middle East, including Israel, Greece, and Cyprus. According to media reports, Ankara signed a $5.6 billion deal to acquire the Eurofighter Typhoon, a 4.5 generation ultra-modern fighter jet, jointly developed by Germany, Britain, Italy, and Spain. Erdogan wants to modernize the Turkish air force and made efforts to purchase F-35 fighter jets from its NATO ally, the United States. However, deal remains uncertain, primarily because of Israeli pressure and Ankara's decision to purchase the S-400 air defence system from Russia. Thus, Turkey has settled for the Eurofighter Typhoon, an advanced fighter jet in its own right, which is comparable to the French Dassault Rafale, and US' F-16 fighters.
