Sen. Rounds Questions Officials on Electromagnetic Spectrum Maintenance for National Defense

Importance of Electromagnetic Spectrum for Defense

• 🎯 General Whiting and General Cotton confirm the vital importance of maintaining access to specific electromagnetic spectrum bands for national defense.
• 💡 The lower 3 GHz band is crucial for radars and sensors that enable detection, tracking, and engagement of targets in all weather conditions, supporting missions like missile defense.
• 🚀 The 7-8 GHz band is essential for satellite communications (satcom), enabling global wideband communication and supporting special missions.

Impact of Spectrum Loss on Operations

• ⚠️ Losing access to these spectrum bands would significantly reduce decision space for leaders and impact operational planning.
• 🛰️ General Cotton highlights that satcom communications are vital for global reach and operations of weapon systems like the bomber force.

B-21 Bomber and Fleet Modernization

• ✈️ The discussion shifts to the B-21 bomber, described as the next-generation, sixth-generation aircraft with all-aspect stealth capability, surpassing the current B-2 Spirit.
• 🇺🇸 The B-21 is set to become the predominant bomber for the U.S. Air Force, moving towards a two-bomber fleet consisting of the B-21 and the modified B-52J.
• 📈 Senator Rounds advocates for accelerating B-21 production to approximately 145 aircraft to avoid a capability gap as legacy systems like the B-1 and B-2 are divested.
• ⏳ Accelerating production is necessary to ensure a sufficient operational fleet as current weapons platforms are worn out.
