A torpedo having a nose section wherein the entire nose section is of a porous material. The volume behind the nose is divided into a plurality of annular chambers and a fluid delivery system provides filtered sea water to the chambers for expulsion through the porous nose. The filtered water passing over the nose and torpedo body is at a rate to alter the trajectory of any particulate matter that would tend to destabilize laminar boundary layer operation.

An underwater vehicle comprising: (a) a body portion extending along a longitudinal axis; (b) a nose portion connected to said body portion; (c) said nose portion being of a porous material; (d) a backing member disposed behind said nose portion so as to form a closed volume therebetween; (e) means defining a plurality of independent chambers around said axis in said closed volume; (f) means for delivering a clean fluid to said independent chambers at respective pressures whereby said fluid will be ejected through said porous nose section from said chambers to alter the trajectory of particulate matter from said nose and body sections as said vehicle moves through the ambient water medium.
