As the Russo-Ukraine War continues into its third year, the limitations of the Russian military, particularly in controlling airspace, have become evident. Notably, the Sukhoi Su-57 “Felon,” a fifth-generation multirole fighter, has underperformed.

The British Royal Navy's latest nuclear-powered submarine, the Astute-class, represents a significant advancement in modern submarine technology.

The Oscar-class submarine, a Soviet-era nuclear-powered cruise missile submarine, first entered service in 1980. Originally designed to target NATO aircraft carriers with P-700 Granit missiles, this class includes the Oscar I and the more advanced Oscar II.

The Soviet-era Yankee class was a nuclear-powered ballistic missile submarine introduced in the 1960s, designed to rival the West's Polaris submarines. Armed with 16 SLBMs and torpedoes, the Yankee was quieter and more streamlined than its predecessors. Operating until 1995, it was a key part of Soviet nuclear deterrence. However, the class is notably remembered for the K-219 tragedy in 1986.

The Invincible-class, built by ThyssenKrupp Marine Systems of Germany, boasts cutting-edge features like extensive automation, large payload capacities, and enhanced underwater endurance.

The Dassault Mirage 4000, despite its advanced design and high capabilities, failed to enter full production, making it a notable example of unrealized potential in aviation history.

The Dassault Mirage F1, first introduced in 1966, was a significant advancement in French aviation, serving as a successor to the Mirage III. Unlike its predecessors with delta wings, the Mirage F1 featured swept wings and conventional tail surfaces, enhancing its maneuverability and reducing runway length requirements.

The F-117 Nighthawk, officially retired by the U.S. Air Force in 2008, continues to be an active presence in the skies, defying typical post-retirement procedures for military aircraft.

The Skipjack-class submarine, operational from the late 1950s to 1990, marked a significant evolution in submarine design for the U.S. Navy, introducing a high-speed teardrop hull and nuclear power.

The Douglas A-4 Skyhawk gets lost in the mix sometimes—but between 1954 and 1979, nearly 3,000 A-4s were produced, making the jet a ubiquitous Cold War staple with the U.S. Navy and U.S. Marine Corps
