F-35 vs F-22 vs F-16: The Ultimate 2025 Fighter Jet Showdown

F-35 vs F-22 vs F-16: The Ultimate 2025 Fighter Jet Showdown

The F-35 has three variants—F-35A, F-35B, and F-35C—and can carry 2× 2000-lb bombs internally (or up to 18,000 lb externally) with a top speed of about Mach 1.6. As of 2025, the F-35A unit flyaway price is roughly $80–$90 million (B/C around $100 million), with production around 150 jets per year and over 1,000 aircraft delivered. The F-22 Raptor entered…

Artificial Intelligence in the Military: How AI Is Reshaping the Future of War

Artificial Intelligence in the Military: How AI Is Reshaping the Future of War

The Pentagon’s Project Maven, now managed by the National Geospatial-Intelligence Agency, uses AI to identify objects in surveillance imagery and speeds target identification timelines from hours to minutes. In 2024, the U.S. tested Scylla AI at Blue Grass Army Depot, which autonomously detected intruders and flagged a guard in seconds, achieving over 96% accuracy distinguishing threats from benign activities. Maven’s…

Unbreakable Military Signals: The Untold Story of Secure Military Communications

Unbreakable Military Signals: The Untold Story of Secure Military Communications

At Bletchley Park in the 1940s, Alan Turing and colleagues decrypted Enigma messages, providing ULTRA intelligence that aided Allied victory. The United States began launching military communications satellites in the 1960s, and by 1982 the second- and third-generation DSCS satellites offered nuclear-hardened, anti-jamming, high-data-rate links worldwide. In 1976, Diffie–Hellman introduced public-key cryptography, and DES was adopted by the United States…

From Battlefields to Space: How Ukraine’s Satellite Program Skyrocketed in 2024-2025

From Battlefields to Space: How Ukraine’s Satellite Program Skyrocketed in 2024-2025

In March 2025 Ukraine’s Ministry of Defense created a Space Policy Directorate to coordinate military space efforts. The crowdfunded ICEYE SAR satellite nicknamed the “People’s Satellite” remained Ukraine’s only satellite under national control, since 2022. Deputy Defense Minister Kateryna Chernohorenko outlined a 2030 roadmap to deploy Ukrainian defense satellites and an air-launch early-warning system. In June 2025 the European Space…

Unstoppable “Unjammable” Drones: How Fiber-Optic Technology is Revolutionizing Warfare and Beyond

Unstoppable “Unjammable” Drones: How Fiber-Optic Technology is Revolutionizing Warfare and Beyond

Fiber-optic drones transmit control commands and live video through a physical fiber tether, making them jam-proof and radio-silent. There are two main categories: Tethered Power Drones (aerial elevators such as AT&T’s Flying COW) that draw power from the ground while carrying a fiber data link, and Fiber-Optic Guided Drones (free-ranging FPVs) that carry a 5–20 km spool of cable for…

Future Combat Air Systems: The Global Race for Sixth-Generation Fighters

Future Combat Air Systems: The Global Race for Sixth-Generation Fighters

FCAS/SCAF aims to field a “system of systems” including a Next-Generation Fighter (NGF) with remote carrier drones and a combat cloud, targeting 2040 in-service and costs exceeding €100 billion. The United States’ NGAD is a “family of systems” with a manned core fighter plus loyal wingman drones, potentially costing around $300 million per fighter and planned to enter service around…

Ghost Signals and Laser Shields: The Pentagon’s 500-Satellite Orbital Defense Net

Ghost Signals and Laser Shields: The Pentagon’s 500-Satellite Orbital Defense Net

In June 2024, Australian astronomers traced a 30-nanosecond radio burst to NASA’s defunct Relay-2 satellite, offline since 1967, likely caused by a micrometeoroid hit or decades of charge buildup. The LES-1 Lincoln Experimental Satellite, silent since 1967, transmitted again in 2012 after 45 years of dormancy. The Pentagon plans a 500-satellite orbital defense net by 2028 to form the Proliferated…

Pentagon’s Space Internet Nightmare: Why the Unified Satellite Network Keeps Stalling

Pentagon’s Space Internet Nightmare: Why the Unified Satellite Network Keeps Stalling

The Pentagon aims to field a software-defined, multi-layer Enterprise SATCOM network that seamlessly routes data across DoD, allied, and commercial satellites in LEO, MEO, and GEO to support Joint All-Domain Command and Control (JADC2). In 2020 the Space Force and DoD CIO committed to the shift, with the SDA launching the National Defense Space Architecture (NDSA), later renamed the Proliferated…

From Jammers to Laser Cannons: Inside the Cutting-Edge Anti-Drone Tech Defending the Skies

From Jammers to Laser Cannons: Inside the Cutting-Edge Anti-Drone Tech Defending the Skies

The NFL reported a 20,000% increase in drone incursions at football games from 2017 to 2023. The global anti-drone market is projected to grow at 27.8% per year this decade. Counter-UAS systems typically use multi-sensor fusion, combining radar, RF analyzers, optical/infrared cameras, and acoustic sensors with artificial intelligence. Rafael’s Drone Dome provides 360° detection with compact radars and is effective…

How AI is Reshaping the Future of Warfare – What You Need to Know Now

The 2017 U.S. Department of Defense project Maven was launched to apply AI-based computer vision to analyze drone surveillance footage in the Middle East, with fielding by year’s end. In 2019, China released its National Defense White Paper announcing the goal of “intelligentized warfare” and a plan to become the world AI leader by 2030. The United States established the…

A Discounted Cash Flow (DCF) model, which estimates company value by projecting future cash flows and discounting them to present value, indicates the stock is 54.1% undervalued with a fair value of $27.44. The model forecasts free cash flow rising from $7.6 million to $281 million by 2030 and $365.4 million by 2035. Additionally, the price-to-sales ratio stands at 0.59x, below the metals and mining sector average, suggesting potential undervaluation relative to peers. These valuation measures provide investors a basis to reassess Nexa amid broader market movements and its strong recent returns.
