Systems and methods for launching and retrieving payloads in aquatic environments employ a platform that is both floatable and submersible at the discretion of and/or under the control of a user, on which submersible objects to be launched, delivered to a subsea location and/or retrieved (the payload) may be located. The submergible platform has a plurality of sealed and/or sealable buoyancy chambers and at least one low pressure gas storage tank having associated fixtures and valves providing introduction of gas to the buoyancy chambers. One or more buoyant elements may be coupled to the submersible platform to support the platform in a submerged condition. A payload docking system providing secure docking of a payload on the platform deck is also disclosed.
