The U.S. Air Force is moving forward with plans to buy five Boeing E-7A Wedgetail intelligence surveillance aircraft, adding to two already under contract, U.S. Secretary of the Air Force Troy Meink told a House subcommittee, signaling a renewed push to restore and modernize airborne early warning capabilities critical for detecting and coordinating against advanced threats.

The announcement, made before a U.S. House subcommittee, highlights the growing urgency of closing capability gaps in airborne surveillance and coordination as near-peer threats expand advanced anti-access and area-denial networks. The move reinforces the role of modern airborne early warning aircraft in enabling joint force integration, real-time targeting, and distributed operations across large theaters.

The Boeing E-7A Wedgetail is built on the Boeing 737-700 airframe and integrates the Northrop Grumman Multi-role Electronically Scanned Array, MESA, radar, which provides 360-degree coverage with no rotating dome. This fixed-array radar allows simultaneous air and maritime surveillance while maintaining a lower mechanical signature and improved reliability compared to legacy AWACS systems.

美國空軍部長梅因克向眾議院小組委員會表示，空軍正推進採購5架波音E-7A「楔尾鷹」情報監控機計畫（此前已有2架依約執行中）。此舉釋出重新推動空中預警能力恢復與現代化的訊號，這對偵測與協調應對先進威脅至關重要。

這項在美國眾議院小組委員會上發布的公告，凸顯了在近同級威脅不斷擴大先進「反介入與區域拒止」網路之際，彌補空中監控與協調能力缺口的急迫性。此舉強化了現代空中預警機在促進聯合部隊整合、即時目標鎖定以及跨大戰區分布式作戰中的角色。

波音E-7A「楔尾鷹」是以波音737-700機體為基礎開發，並整合諾斯洛普格魯曼公司的「多用途電子掃描陣列」雷達，該雷達提供360度涵蓋範圍且無需旋轉雷達罩。這種固定陣列雷達允許同時進行空中與海上監視，與傳統的空中預警管制系統相比，其機械特徵較低且可靠性更高。
