Sentry Staff Tensions between strategic competitors, North Korea’s persistent nuclear weapons expansion and Russia’s attempts to shift Europe’s balance of power with its war against Ukraine have contributed to a coalescing among the United States and its Allies and Partners to modernize strategies that more effectively combat 21st century security threats. Geopolitical changes, particularly in the Indo-Pacific and European regions, threaten to upend decades of peace and stability. Alliances like NATO have met these challenges by more closely linking defense plans that span the globe and battlespace domains. “Never before have NATO and defense plans been so closely interlinked,” Royal…

Sentry Staff Security analysts say the accession of Finland and Sweden into the 75-year-old NATO Alliance will strengthen each nation’s own security posture, better protect the Baltic Sea and Europe’s eastern flank, and bolster those regions’ air and sea capabilities. After decades of military nonalignment, the two nations asked to join the Alliance in 2022 — a decision prompted by Russia’s invasion of Ukraine. The move marks the most significant NATO expansion since the Alliance welcomed members from Eastern Europe after the Soviet Union collapsed in 1991. It is also a blow to Russian President Vladimir Putin, who has sought…

Sentry Staff For 75 years, the United States has stood with, and stood up for, fellow members of NATO, a nuclear alliance that has proven itself as a primary success story for collective defense.

The spirit of collective deterrence outlined in Article 5 — an attack on one is…

In addition to the U.S. Army, the Navy, the Marine Corps and the Air Force also maintain equipment stocks on land and at sea. Materiel at these…

About 60 countries including the United States endorsed a “blueprint for action” in September 2024 to govern responsible use of artificial intelligence (AI) in the military, but the People’s Republic of China (PRC) was among those that refused to support the legally non-binding document. The Responsible AI in the Military Domain summit in Seoul, the second of its kind, followed one held in The Hague in 2023. At that time, around 60 nations including the PRC endorsed a modest “call to action” without legal commitment. Government representatives said this latest plan was more action-oriented, in keeping with advanced discussions and…

NASA’s space shuttle system operated in low Earth orbit for 30 years before its retirement in 2011. However, the U.S. space agency’s replacement for these vehicles, the Orion spacecraft, returned to the conical capsule design familiar from Mercury, Gemini and Apollo missions. This was because NASA intended that this newer craft be used for exploring targets beyond low Earth orbit. In recent years, however, there’s been a return of the spaceplane design. Since 2010, the U.S. Space Force (and formerly the U.S. Air Force) has been launching a robotic spaceplane called the X-37B into low Earth orbit on classified missions.…
