These AUVs will be responsible for defending the submarine, monitoring and listening to the surrounding environment. This is crucial because, in the future, AUVs are expected to pose the most significant threat to submarines. Heavy and few torpedoes are not effective for dealing with small and numerous AUVs. Therefore, the internal layout of future military submarines should be modified to enable the widespread use of AUVs. The two significant distinctions between AUVs and torpedo launchers are that, firstly, AUVs must be recoverable and not disposable, and secondly, AUVs must be deployed in large numbers simultaneously. As a result, their launchers will be different. In this article, 13 methods are proposed for the deployment of AUVs, and the advantages and disadvantages of each method are also listed. Also, due to the requirement for special launchers for AUVs, the sixth-generation submarines will feature double-hull or combined hull designs, whereas most military submarines in this century have been predominantly single-hull. The article also examines the issue of &quot;ocean transparency,&quot; which poses the greatest threat to future submarines.</span><span style="font-size:10.0pt"></span></span></span><br> &nbsp; AUV,Naval Submarine,Mother Submarine,Future Submarine,Double Hull Submarine. 44 60 http://ijmt.ir/browse.php?a_code=A-10-450-7&slc_lang=en&sid=1 Farzad Eskandari f.eskandari9@gmail.com 10031947532846004612 10031947532846004612 No Marine Industries Organization, Tehran, Iran Mohammad Moonesun m.moonesun@gmail.com 10031947532846004613 10031947532846004613 Yes Faculty of Civil Engineering, Shahrood University of Technology, Shahrood, Iran Ataollah Gharechae a.gharehchahi@gmail.com 10031947532846004614 10031947532846004614 No Chabahar Maritime University, Maritime Engineering College, Chabahar, Iran
