未來的作戰系統,越來越有星戰的味道。日本防衛省在2024年9月宣布,為應對小型無人機的威脅,將從明年起展開「艦載用雷射系統」的研究試作,並公開了相關的概念圖。
近年來無人機技術飛速發展,不僅能用於偵察,還能進行自殺式攻擊。此外,未來可能出現大量無人機協同攻擊的「蜂群攻擊」,這被視為重大威脅。由於無人機製造成本低廉,若以傳統的飛彈攔截,成本效益會很低。
針對這種新威脅,防衛省提出開發「艦載用雷射系統」作為解決方案。此系統初期開發具有「軟殺」功能的雷射系統,通過光學干擾等方式削弱敵方無人機,而非進行物理破壞。雷射能連續發射,能有效應對大批無人機的來襲,僅需電力支援,不需額外補給彈藥。

Dr. Seuss
Joseph Addison
4. “You can find magic wherever you look. Sit back and relax, all you need is a book."
Dr. Seuss
5. “ Books are a uniquely portable magic."
Stephen King
6. “There is no friend as loyal as a book."
Ernest Hemingway
7. “ The reading of all good books is like a conversation with the finest minds of past centuries."
René Descartes

hoppern.

[Sense 2, from the shaking or hopping motion of grain hoppers as grain passed through them to the mill.]
A tray, or chute, that accepts input to a mechanical device, such as a disk duplicator or printer. In the days of punch cards, millions of cards were numerically or alphabetically organized by placing them into the hopper of a card sorter, taking them out of all the stackers and putting them back into the hopper for the next card column.
