The MK 41 VLS is available in three different sizes to meet most hull and mission requirements:

• The Strike length MK 41 is the largest system accommodating missiles from every warfare mission.
• The Tactical length is over 7 feet shorter than the Strike length and can accommodate a variety of missiles up to approximately 18.5 feet in length.
• The Self-Defense Launcher (SDL) is specifically designed for ship self defense. SDL is shorter and lighter than the other variants. Its size and weight make it ideal for smaller ships such as corvettes and frigates and for aircraft carriers with limited deck and hull space
