The armor system uses armor stacks of ceramic tiles connected to layers of glass. The armor stacks are then adhered to the inside of a cover box. The cover box is then secured to a base and then covered with a cloth impregnated with an adhesive. ## Claims ### Claim 1 An armor system, comprising: a plurality of armor stacks, wherein each armor stack comprises; a ceramic tile with a first side and a second side; a first layer of adhesive on the first side of the ceramic tile; a first sheet of glass with a first side and a second side, wherein the first side of the first sheet of glass is contiguous to the first layer of adhesive; a second layer of adhesive on the second side of the first sheet of glass; a second sheet of glass with a first side and a second side, wherein the first side of the second sheet of glass is contiguous to the second layer of adhesive; a third layer of adhesive on the second side of the second sheet of glass; and a third sheet of glass with a first side and a second side, wherein the first side of the third sheet of glass is contiguous to the third layer of adhesive; and a cover box, with an open side and with an interior and exterior wherein the plurality of armor stacks are on the interior of the cover box. ### Claim 2 (depends on 1) The armor system, as recited in claim 1, further comprising a first base plate covering the open side of the cover box and mechanically connected to the cover box. ### Claim 3 (depends on 2) The armor system, as recited in claim 2, further comprising a second base plate covering the open side of the cover box and mechanically connected to the cover box. ### Claim 4 (depends on 3) The armor system, as recited in claim 3, further comprising, a cloth impregnated with an adhesive covering the exterior of the cover box. ### Claim 5 An armor system, comprising: a plurality of armor stacks, wherein each armor stack comprises; a ceramic tile with a first side and a second side; a first layer of adhesive on the first side of the ceramic tile; a first sheet of glass with a first side and a second side, wherein the first side of the first sheet of glass is contiguous to the first layer of adhesive; a second layer of adhesive on the second side of the first sheet of glass; and a second sheet of glass with a first side and a second side, wherein the first side of the second sheet of glass is contiguous to the second layer of adhesive; a cover box, with an open side and with an interior and exterior wherein the plurality of armor stacks are on the interior of the cover box; and a first base plate covering the open side of the cover box and mechanically connected to the cover box. ### Claim 6 (depends on 5) The armor system, as recited in claim 5, further comprising a second base plate covering the open side of the cover box and mechanically connected to the cover box. ### Claim 7 (depends on 6) The armor system, as recited in claim 6, further comprising, a cloth impregnated with an adhesive covering the exterior of the cover box. ### Claim 8 (depends on 7) The armor system, as recited in claim 7, wherein the ceramic tile is made of silicon carbide, and wherein the box cover is steel. ### Claim 9 (depends on 8) The armor system, as recited in claim 8, wherein the first sheet of glass and the second sheet of glass are Pyrex. ### Claim 10 A method of manufacturing an armor system, comprising the steps of: manufacturing a plurality of armor stacks, comprising the steps of: placing first layers of adhesive on first sides of a plurality of tiles; placing first sides of a plurality of first sheets of glass on the first layers of adhesive; placing second layers of adhesive on second sides of the plurality of the first sheets of glass; and placing first sides of a plurality of second sheets of glass on the second layers of adhesive; placing a layer of adhesive in a cover box; placing the plurality of armor stacks in the cover box; filling the cover box with adhesive; and securing a base plate to the cover box. ### Claim 11 (depends on 10) The method of manufacturing an armor system, as recited in claim 10, further comprising the steps of: placing third layers of adhesive on second sides of the plurality of second sheets of glass; and placing first sides of a plurality of third sheets of glass on the third layers of adhesive, and wherein the step of placing the plurality of armor stacks in the cover box, places the third sheets on the layer of adhesive in the cover box. ### Claim 12 (depends on 11) The method of manufacturing an armor system, as recited in claim 11, further comprising the steps of; placing spacers around the cover box; covering the spacers and the cover box with cloth; and impregnating the cloth with an adhesive. ### Claim 13 (depends on 12) The method of manufacturing an armor system, as recited in claim 12, further comprising, the step of mounting the base plate on the hull of the vehicle. ### Claim 14 An armor system, comprising: a plurality of armor stacks, wherein each armor stack comprises; a silicon carbide rile with a first side and a second side; a first layer of adhesive on the first side of the silicon carbide tile; a first sheet of glass with a first side and a second side, wherein the first side of the first sheet of glass is contiguous to the first layer of adhesive; a second layer of adhesive on the second side of the first sheet of glass; and a second sheet of glass with a first side and a second side, wherein the first side of the second sheet of glass is contiguous to the second layer of adhesive.
