Fenduzhe 奋斗者号，是中国自主研发的万米载人潜水器，于2016年立项，由蛟龙号、深海勇士号载人潜水器的研发力量为主的科研团队承担 。2020年6月19日，中国万米载人潜水器正式命名为“奋斗者号” 。
2020年10月27日，奋斗者号在马里亚纳海沟成功下潜突破1万米达到10058米，创造了中国载人深潜的新纪录。11月10日8时12分，奋斗者号在马里亚纳海沟成功坐底，坐底深度10909米，刷新中国载人深潜的新纪录。2021年10月，“奋斗者”号已在马里亚纳海沟正式投入常规科考应用。

通常认为，深度超过 2,00 米 的海域属于深海区域。在这一深度以下，光照几乎消失，水压极大，环境与浅海截然不同，孕育着许多适应极端环境的特殊生物，也有着独特的地质结构。
有些鲸鱼，例如柯氏喙鲸，能够下潜到深海区域，其最深下潜记录可达约 2,992 米 。鲸鱼的这种深潜能力是为了觅食等生存需求，它们在深海的活动也反映了深海生态系统中生物的多样性和适应性。
著名的泰坦尼克号邮轮在 1912 年沉没于北大西洋，其残骸位于约 3,800 米 的深海处。这一深度的海底环境使得泰坦尼克号的残骸保存状况具有独特的研究价值，也让人们对其沉没的历史事件有了更多的探索线索。
“奋斗者” 号是中国自主研发的全海深载人潜水器，它成功下潜至马里亚纳海沟 10,909 米 处，这一深度彰显了中国在深海探测领域的先进技术，也为人类探索深海奥秘、开展深海科学研究提供了重要支撑。
