「無人機蜂群」來襲！美軍3D列印打造超低價無人機模擬敵襲

當無人機已成為新時代的火線武器，美軍正以更靈活、更低成本的方式，重新定義戰場演訓模式。透過3D列印技術，美軍正量產「幾乎便宜到離譜」的訓練用無人機，模擬敵方蜂群攻擊，直接拉近實戰與訓練的距離。

As drone swarms become a defining threat in modern warfare, the U.S. Army is turning to 3D printing to produce ultra-low-cost UAVs for frontline training—replicating hostile aerial threats at scale without breaking the bank.

這項計畫並非紙上談兵。由美國陸軍未來司令部（AFC）領軍執行，搭配第101空降師及陸軍物資司令部（AMC）共同參與，被內部稱為「衝刺計畫」（Sprinting Program），其目標明確：在駐地日常訓練中，讓士兵學會如何對抗一整群突如其來的無人機。

Dubbed the “Sprinting Program,” the initiative is spearheaded by Army Futures Command and supported by the 101st Airborne Division and Army Materiel Command. Its primary goal? To expose troops to swarm drone attacks as part of routine garrison-level live-fire training.

「你不能等到戰場上才學怎麼反制無人機蜂群，」陸軍未來司令部司令詹姆斯·雷尼（James Rainey）上將坦言，這類模擬無人機必須「簡單到不能再簡單」，不需要昂貴的感測器或精密鏡頭，只要飛得起來、能被打下來就好。

“We can’t wait until we’re in combat to learn how to respond to drone swarms,” said Gen. James Rainey, commander of Army Futures Command. “These training drones need to be ridiculously cheap. No Gucci cameras. No fancy sensors. Just get them airborne and knock them down.”

這樣的構想，其實正是從烏克蘭與緬甸等地的實戰經驗中學來的。這些衝突區域大量利用3D列印製造攻擊型無人機，成為全球戰術革新的重要範例。

This concept draws directly from battlefield lessons in Ukraine and Myanmar, where both forces have relied on 3D-printed drones to overwhelm opponents at a fraction of the cost.

目前美軍每週可製造約10架重約9公斤的訓練無人機，主要結構由伊利諾州的岩島兵工廠（Rock Island Arsenal）3D列印製作，並送往賓州托比哈納陸軍機廠（Tobyhanna Army Depot）完成電子設備的安裝與整合。

Each week, about 10 small drones (under 9 kg) roll off the line. The Rock Island Arsenal in Illinois handles the 3D-printed airframes, while Tobyhanna Army Depot in Pennsylvania installs the electronics—highlighting a collaborative logistics network designed for scale.

陸軍物資司令部代理司令莫漢中將指出，若決定擴大產能，未來可能改採更快的「射出成型」（injection molding）技術，每月生產量上看1萬架，專供國家訓練中心（NTC）與聯合戰備訓練中心（JRTC）等核心演訓據點使用。

If the Army chooses to scale up, production may shift to injection molding—boosting output to 10,000 units per month. These would primarily be deployed to major training hubs like the National Training Center and the Joint Readiness Training Center.

這場無聲的科技演習，正在改變美軍的備戰邏輯。從「成本最低」反制到「模擬最真實」的訓練目標，一場針對無人機蜂群的全新軍事思維，已然成形。

This quiet technological shift is redefining U.S. military preparedness—fusing cost-efficiency with battlefield realism in the age of drone swarms.
