حسنا لنأخذ غواصة فاتح كمثال فهي غواصة فريدة من حيث التصميم و لا تستند لأي تصميم كوري أو صيني أو روسي معروف واستغرقت ايران أكثر من 10 سنوات لتطويرها وهذا يدل ان ايران تحقق تقدما في صناعتها الدفاعية وهذا الامر لا يمكن انكاره
After years of a methodical national program Iran has finally joined the exclusive club of nations able to design and build large submarines. Starting with very crude midget submarines in the 1980s, the Iranian indigenous submarine program has progressed through several midget submarines and now, with the commissioning of Fateh, full-size submarines. There has been significant external influence along the way, notably from North Korea who very visibly supplied MS-29 Yono Class midget submarines which were put into serial production locally as the IS-120 Ghadir Class. And there has also been some liaison with Russian and Chinese organizations. Ultimately however the Fateh is a legitimate indigenous product and Iran deserves some credit in this regard.
