A radially locked subsea housing includes a low pressure housing having upper and lower radial lock regions, each of which regions includes a radial interference surface that is between vertical to only slightly tapered in orientation. A high pressure housing also has upper and lower radial lock regions, each of which regions includes a radial interference surface that is slightly greater in radial diameter than the corresponding interference surface of the low pressure housing. The interference surfaces of the upper and lower radial lock regions form upper and lower interference fits, respectively, between the high pressure and low pressure housings when the housings are assembled subsea. The low pressure housing further includes a landing shoulder defining a landing surface that is substantially more tapered in orientation than are the interference surfaces of the upper and lower radial lock regions, and the high pressure housing includes a landing shoulder defining a landing surface formed to land on the landing surface of the low pressure housing when the housings are assembled subsea. In an alternative embodiment, a zero-clearance, axially extended fit is employed at one or both of the radial lock regions.
