The Defiant has a 5th sub-deck below the 4th deck in the nacelles for maintenance access.

Please note, due to design limitations, the Defiant class cannot land on a planetary body. It is also unsuited for atmospheric flight, and this should be avoided wherever possible. Landing struts are primarily used while docked internally with a large starbase.
