Eye of God" helmet of the pilots F-35!

Eye of God" helmet of the pilots F-35

An F-35 pilot’s helmet costs more than a Ferrari and takes two days to get fitted!
If you’re looking for a helmet for the advanced F-35 Lightning II, then get ready to put down enough money to buy a Ferrari sports car, undergo a two-day fitting process, keep your hair generally in the same shape, avoid putting on weight, and check in three times a year to make sure it still fits perfectly.

At least, that seems to be the process described in a new Air Force press release detailing just how much work it takes to keep one part of the $78 million F-35 fighter ready to fly.

“Pilots come in and put on all their gear so we can double-check to make sure everything fits properly and without issue,” said Staff Sgt. AJ Arteaga, an aircrew flight equipment reservist with the 419th Operations Support Squadron at Hill Air Force Base, Utah.

“Small things such as a new haircut or a couple of pounds gained could cause the helmet to not fit correctly,” Arteaga said.

The B-2 Spirit bomber, commonly known as the Stealth Bomber, has indeed drawn inspiratio from certain aspects of bird anatomy
particularly in terms of its aerodynamic design and stealth features. While it may not have been directly modeled after a specific falcon bird, elements of avian physiology and flight dynamics have influenced the design of the B-2. Here are some ways in which the B-2's design reflects principles observed in birds:

Sleek, Flying-Wing Shape: The B-2 features a distinctive flying-wing design, which reduces its radar cross-section and enhances its stealth capabilities. This shape is reminiscent of certain bird species, including falcons, which have streamlined bodies that minimize air resistance during flight.

Smooth Contours and Tapered Edges: Like the streamlined feathers of birds, the B-2's smooth contours and tapered edges help reduce turbulence and minimize radar reflections, allowing it to fly undetected in hostile airspace.

Feathering and Wing Morphing: While the B-2 does not have movable feathers like birds, its advanced composite materials and flexible structures enable subtle changes in wing shape and surface texture to optimize aerodynamic performance and reduce radar signature.

Silent Flight: Similar to birds of prey like falcons, which are known for their silent flight, the B-2's engines are designed to operate quietly, further enhancing its stealth characteristics.

High Aspect Ratio Wings: The B-2's high aspect ratio wings, with their long span and narrow chord, contribute to its efficient aerodynamics and long-range capabilities, similar to the wings of soaring birds like falcons.

While the B-2 bomber's design is primarily driven by technological requirements and military objectives, its resemblance to certain aspects of bird anatomy underscores the ingenuity of engineers in leveraging nature's principles to achieve optimal performance in aerospace applications.

F-22 Raptor the most scariest Fighter jet in the 25 years

The F-22 Raptor is widely considered to be the most "scary" fighter jet in the last 25 years due to its unmatched combination of stealth technology, supercruise capability, maneuverability, and advanced avionics, making it a formidable air superiority fighter that can engage and potentially destroy enemy aircraft before they even detect its presence.

Key points about the F-22 Raptor:
• Stealth technology: The F-22's design minimizes its radar signature, making it very difficult to detect by enemy radar systems.
• Supercruise: It can fly at supersonic speeds without using afterburners, allowing for sustained high speeds during combat.
• Advanced sensors and avionics: The F-22 has highly integrated systems that provide pilots with exceptional situational awareness and target identification capabilities.
• Maneuverability: Its thrust vectoring technology enables excellent agility in close-quarters combat.

SEA SHADOW STEALTH 🇺🇸🇺🇸🇺🇸

SEA SHADOW STEALTH 🇺🇸🇺🇸🇺🇸

The Sea Shadow, or "IX-529," was an experimental stealth ship developed by Lockheed Martin and the U.S. Navy in the 1980s to test cutting-edge stealth technology for naval vessels. With its flat, faceted hull and black radar-absorbent coating, it was designed to evade detection by enemy radar.

Though never intended for active service, Sea Shadow played a crucial role as a testbed for innovations that influenced future ships, including the Zumwalt-class destroyers. After years of testing, it was retired and stored until being auctioned off in 2012 and scrapped in 2014. Despite its short-lived operational history, Sea Shadow's legacy continues to shape naval stealth technology.
