Pentagon and CBO Clash Over Golden Dome Missile Defense System Cost Estimates

Pentagon and CBO Clash Over Golden Dome Missile Defense System Cost Estimates

Federal officials are in disagreement regarding the projected costs and technological scope of the Pentagon’s Golden Dome missile defense network. The Congressional Budget Office’s (CBO) national security division head, David Mosher, defended their estimate of at least $1.2 trillion over 20 years for President Trump’s vision of Golden Dome. This estimate is based on publicly available data and past research, utilizing current technology like Patriot missile batteries and Aegis Ashore to predict the network outlined in President Trump’s January 2025 executive order for an 'Iron Dome for America.' In contrast, Space Force Gen. Michael Guetlein, the program manager for Golden Dome, dismissed the CBO's figure as an 'uninformed myth,' stating that it does not accurately reflect what the Pentagon is building. The Pentagon has projected a more modest cost of $185 billion to deploy Golden Dome over the next decade. Guetlein emphasized that the CBO's approach uses a 'cookie-cutter' method that misrepresents the act...

U.S. Army Adopts New Strategy for Rapid Electronic Warfare Capability Deployment Amidst Budget Constraints

U.S. Army Adopts New Strategy for Rapid Electronic Warfare Capability Deployment Amidst Budget Constraints

The U.S. Army is implementing a new strategy to rapidly acquire and deploy electronic warfare (EW) capabilities to soldiers, despite a lack of new program starts in the fiscal year 2027 budget. This approach leverages existing prototypes and broad requirements from other programs. Key to this strategy are two recently published documents: a Characteristics of Need (CoN) for Electromagnetic Spectrum Operations (EMSO) systems, which outlines general requirements, and the Rapid Electromagnetic Warfare & Signals Intelligence Commercial Solutions Offering (REWSI) Commercial Solutions Opening (CSO), a library of commercial capabilities. Mark Saxon, deputy project manager for Electromagnetic Warfare & Collection, indicated that this allows the Army to experiment with small quantities of systems, particularly with V Corps, which has troops deployed in Eastern Europe. The REWSI will enable the Army to select capabilities from a commercial library, fostering competition and ensuring tailored solutions for different ...

U.S. Missile Defense Agency Awards X-Bow Systems $11 Million for Low-Cost Interceptor Development

U.S. Missile Defense Agency Awards X-Bow Systems $11 Million for Low-Cost Interceptor Development

The U.S. Missile Defense Agency (MDA) has granted X-Bow Systems a contract worth nearly $11 million to develop and flight-test a Low-Cost Interceptor. This initiative is part of the MDA’s Rapid Response Small Launcher Technology program and its broader Low-Cost Interceptor initiative. The goal is to create interceptor technologies that can reduce the cost of countering ballistic, hypersonic, and cruise missile threats to below $750,000 per round. Current missile defense weapons, such as the Patriot interceptor, can cost between $2 million and $4 million each. X-Bow Systems plans to achieve this cost reduction by integrating the development of the interceptor and its solid rocket motor in-house, thereby controlling production costs and output. Founder and CEO Jason Hundley emphasized that the existing U.S. supplier base cannot meet the growing demand for missile defense, highlighting the need for innovative approaches to production.

UK A-Level Examination System Grades Students from A to E, with Concerns Over Subject Withdrawals

UK A-Level Examination System Grades Students from A to E, with Concerns Over Subject Withdrawals

The UK's A-level examination system grades students from A (Outstanding) to E (minimum passing grade), with a U indicating a failing grade. Recent developments indicate that the Council for the Curriculum, Examinations & Assessment (CCEA) in Northern Ireland is withdrawing several GCSE and A-level subjects, including German, Economics, and Engineering, from its offerings by the end of the decade. This decision is based on factors such as candidate entry patterns and the long-term sustainability of these subjects. For instance, while 587 students took GCSE German in 2025, only 49 pursued it at A-level. Other subjects being withdrawn include GCSEs in Leisure Travel and Tourism, Learning for Life and Work, and Contemporary Crafts, as well as the A-level in Professional Business Services. Schools wishing to continue offering these subjects will need to do so through English or Welsh exam boards.
