美國空軍與美國海軍共同研發的GBU-75「聯合直接攻擊彈藥－長程型」（JDAM LR）近日正式獲准進入初始量產（Initial Production）階段，象徵這款新一代長程精準打擊武器朝實戰部署邁出重要一步，可望大幅提升美軍遠距精準打擊與防區外攻擊能力。

The jointly developed GBU-75 Joint Direct Attack Munition Long Range (JDAM LR) program has officially been cleared to enter initial production, marking a major step toward operational deployment. The new weapon is expected to significantly enhance the U.S. military's long-range precision strike and stand-off attack capabilities.

波音獲首份量產合約　推動武器部署

Boeing Receives First Production Contract

美國海軍已向波音公司授予價值7,500萬美元的未定義合約（Undefinitized Contract Action），生產JDAM LR所使用的BSU-111/B彈體投放模組（Payload Delivery Unit），為未來量產與部隊部署奠定基礎。此項進展距離JDAM LR今年4月於加州完成首次飛行測試僅約四個月，也代表波音近1億美元自主研發投資開始獲得成果。

The U.S. Navy has awarded Boeing a US$75 million undefinitized contract to manufacture the BSU-111/B Payload Delivery Units for the JDAM LR. The award lays the groundwork for initial production and future operational deployment. The milestone comes just four months after the weapon completed its first flight tests in California and follows Boeing’s nearly US$100 million internal investment in the program.

波音精準打擊系統副總裁Bob Ciesla表示，首份量產合約代表JDAM LR計畫的重要里程碑，證明波音能以遠低於其他同級武器的成本，提供具備長程精準打擊能力的新一代武器系統。

Bob Ciesla, Vice President of Boeing Precision Engagement Systems, said the first production contract represents a major milestone for the JDAM LR program, demonstrating Boeing’s ability to deliver long-range precision strike capability at significantly lower cost than comparable systems.

射程突破556公里　超越JDAM-ER七倍

Range Exceeds 556 Kilometers—Seven Times Greater Than JDAM-ER

JDAM LR是在現役JDAM精準導引套件基礎上發展而成，可將傳統無導引炸彈轉換為具備遠程滑翔能力的精準武器，可執行對地打擊、對海攻擊及空中布雷等多元任務。

The JDAM LR is an evolution of the existing JDAM precision guidance kit, transforming conventional unguided bombs into long-range precision-guided weapons capable of conducting land attack, maritime strike, and aerial mining missions.

該型武器可攜帶500磅（約226公斤）級戰鬥部，最大射程超過300浬（約556公里），相比現役JDAM-ER約40浬（74公里）的射程提升超過七倍，大幅增加載機的防區外打擊距離與生存能力。

Carrying a 500-pound (226-kilogram) class warhead, the JDAM LR has a maximum range exceeding 300 nautical miles (556 kilometers), more than seven times the approximately 40-nautical-mile range of the current JDAM Extended Range (JDAM-ER), greatly expanding stand-off strike distance and aircraft survivability.

相容多型戰機與轟炸機　提升聯合作戰能力

Compatible With Fighters and Strategic Bombers

JDAM LR可整合至所有已取得JDAM認證的作戰平台，包括美國海軍F/A-18E/F「超級大黃蜂」戰機，以及美國空軍B-52「同溫層堡壘」戰略轟炸機等，使各型載台均可快速獲得長程精準打擊能力，提升跨軍種聯合作戰效能。

The JDAM LR is designed for integration with any aircraft already certified to employ standard JDAM weapons, including the U.S. Navy’s F/A-18E/F Super Hornet and the U.S. Air Force’s B-52 Stratofortress strategic bomber, allowing multiple platforms to rapidly gain long-range precision strike capability.

波音擴建產線　加速服役進程

Boeing Expands Production Ahead of Operational Fielding

波音目前正於密蘇里州聖查爾斯（St. Charles）廠區規劃JDAM LR生產設施，同時持續進行武器認證與各型機整合測試，為後續正式服役與大規模量產做好準備。隨著JDAM LR投入生產，美軍未來將能以相對低成本快速擴充遠距精準打擊火力，進一步提升嚇阻與作戰能力。

Boeing is preparing dedicated manufacturing space for the JDAM LR at its St. Charles, Missouri, facility while continuing qualification and aircraft integration activities ahead of operational fielding. Once fully deployed, the JDAM LR is expected to provide the U.S. military with a cost-effective means of rapidly expanding its long-range precision strike capability and overall combat effectiveness.
