The governor shall organize and maintain within this state on a cadre or reserve basis naval forces capable of being expanded and trained to defend this state whenever the Ohio national guard, or a part thereof, is employed so as to leave this state without adequate defense, and whenever necessary to assist and maintain the public peace in case of a disaster or emergency as determined by the governor. Such forces shall not be used in disturbances that are civil in nature, including but not limited to riots and strikes. Such forces shall be known as the Ohio naval militia. Such forces shall be a part of the organized militia of this state. The Ohio naval militia shall consist of not more than three ship companies as provided in sections 5921.02 to 5921.16 of the Revised Code.
