The B-21 is a free printable 3D model from MakerWorld by XJBHC. 为我助力这次带来的是B-21，共有12个可动部件，包括背部可动鳍片、机腹弹舱、机翼等。安装方式见下图：B-21“突袭者”是美国空军新一代隐身战略轰炸机，由诺斯罗普·格鲁曼研制，2022年公开、2023年11月首飞。它延续B-2飞翼布局，但尺寸更小、隐身材料与进气道设计更优化，强调“极低可探测”和穿透强防空网能力。. You can download the STL file from the original listing below and print it at home.

About this model

为我助力这次带来的是B-21，共有12个可动部件，包括背部可动鳍片、机腹弹舱、机翼等。安装方式见下图：B-21“突袭者”是美国空军新一代隐身战略轰炸机，由诺斯罗普·格鲁曼研制，2022年公开、2023年11月首飞。它延续B-2飞翼布局，但尺寸更小、隐身材料与进气道设计更优化，强调“极低可探测”和穿透强防空网能力。采用两名机组、两台涡扇发动机，最大起飞重量约82吨，航程约8000公里级，弹舱可携常规精确制导弹药与核弹，具备核常兼备打击能力。B-21还被定义为信息化节点，可侦察、中继、协同无人机作战。目前进入低速生产，预计2026—2027年服役，将逐步替换B-2、B-1B，成为美军未来空基核常打击核心。
