Patent number: 11447219Abstract: A weaponized UUV has a sliding barrel and accessible breech. The barrel slides in response to the firing of a projectile, and moves a first distance un-arrested, providing time for the projectile to clear the barrel. After the projectile clears the barrel, a recoil mechanism engages the barrel, transferring the recoil load to the hull of the UUV.Type: GrantFiled: January 17, 2020Date of Patent: September 20, 2022Assignee: Advanced Acoustic Concepts, LLCInventors: Antonio Paulic, Terry Miller

Patent number: 11073369Abstract: An article comprising an electronic safe-arm and fire (ESAF) device for a supercavitating cargo round (SCR) includes discrete electronics, a high-voltage capacitor, a high-voltage switch, and an exploding foil initiator. The discrete electronics includes digital-delay timer circuits, discrete logic circuits, accelerometers, and circuitry for enabling the high-voltage switch. In a method for implementing the safe and arm protocols, sensor readings from sensors on a weaponized UUV are obtained and, when certain conditions are achieved, remove inhibit signals are forwarded to a controller onboard the UUV. When such signals are received in a specified order, and within certain optional specified time delays, the controller arms the ESAF within the SCR. After the SCR fire and leaves the barrel on the UUV, the ESAF monitors certain acceleration/deceleration conditions unique to supercavitation, and applies same to determine whether to detonate the SCR's energetic payload.Type: GrantFiled: January 2, 2020Date of Patent: July 27, 2021Assignee: Advanced Acoustic Concepts, LLCInventors: Antonio Paulic, Benjamin Gary Conaway, John Walter Rapp, John Granier

Patent number: 8438977Abstract: A supercavitating projectile is disclosed that has deployable fins. The fins are pivotally coupled to the body of the projectile. The fins have two primary states: stowed within a recess at the surface of the projectile and deployed to a radially-extended position relative to the body of the projectile. The fins deploy as the projectile leaves its launch tube. The fins function as a control surface, interacting with the wall of the vapor cavity in which the supercavitating projectile travels.Type: GrantFiled: December 25, 2008Date of Patent: May 14, 2013Assignee: Lockheed Martin CorporationInventors: Antonio Paulic, Robert M. Krass

Patent number: 8250984Abstract: In accordance with an embodiment of the invention, a submunition is contemplated having a submunition body, an explosive payload housed within said submunition body and an elongated delay member housed within the submunition body, the elongated delay member coated with at least one reactive material that provides a controlled time delay between submunition impact and detonation of the explosive payload. The submunition may also comprise an elongated pendulum having a hollow core sized to receive said elongated delay member, the elongated pendulum adapted to be movable between a locked position that mitigates likelihood of inadvertent detonation of the explosive payload and an unlocked position that enables detonation of the explosive payload.Type: GrantFiled: August 31, 2009Date of Patent: August 28, 2012Assignee: Lockheed Martin CorporationInventors: Antonio Paulic, Lance Benedict

Publication number: 20120210857Abstract: An underwater gun for firing stacked munitions includes external propellant bays. In some embodiments, after a first munition is launched from the barrel of the launcher, propellant in one of the external propellant bays is ignited. The gas that is generated upon ignition is routed to the bore of the barrel and expels water that is in the barrel. A munition is then immediately launched through the cleared barrel.Type: ApplicationFiled: October 29, 2009Publication date: August 23, 2012Applicant: LOCKHEED MARTIN CORPORATIONInventor: Antonio Paulic

Publication number: 20120210856Abstract: Stacked munitions are launched at high velocity from a launcher by redirecting, to the barrel of launcher, the static load that would otherwise be borne by the nose the projectile in position three for launch. This is accomplished via a load-redirecting pusher plate comprising a load-receiving surface and a plurality of compression members.Type: ApplicationFiled: October 1, 2009Publication date: August 23, 2012Applicant: LOCKHEED MARTIN CORPORATIONInventor: Antonio Paulic

Patent number: 8245645Abstract: A mine defeating projectile includes a housing defining an inner cavity, a plurality of channels extending through a front surface of the housing and to the inner cavity, and a plurality of cutout sections extending through as side wall thereof. The projectile further includes a fragmentation sleeve disposed in the inner cavity of the housing and a slider sleeve disposed in the inner cavity of the housing abutting an aft end of the fragmentation sleeve. The slider sleeve includes an explosive train and the slider sleeve is frangibly attached to the housing. The projectile further includes a finned section attached to an aft end of the housing. The finned section defines a protrusion for initiating the explosive train. The protrusion is spaced apart from the explosive train.Type: GrantFiled: February 9, 2010Date of Patent: August 21, 2012Assignee: Lockheed Martin CorporationInventors: Antonio Paulic, Lance Benedict

The one or more attachment members are coated with a thermally reactive material. A projectile and cartridge assembly has a shear pin, a projectile having a first cutout portion, the cutout portion sized to receive the shear pin. The assembly also includes a sabot configured to house the projectile and having a second cutout portion, the second cutout portion sized to receive the shear pin. The cutout portion is positioned to provide an offset region between an aft end of the projectile and a base of the sabot.Type: GrantFiled: March 23, 2009Date of Patent: July 17, 2012Assignee: Lockheed Martin CorporationInventors: Jyun-Horng Fu, Antonio Paulic

Patent number: 8047135Abstract: Some embodiments of the invention provide a dart that contains an HE payload, two time-delay fuses, one providing a relatively longer delay and the other providing a relatively shorter delay and two triggering mechanisms for triggering the fuses. The first triggering mechanism, which triggers on contact with a mine lid, triggers the relatively shorter time-delay fuse. The second mechanism, which triggers on overburdening exposure to water, sand, or soil, triggers the relatively longer time-delay fuse.Type: GrantFiled: November 5, 2008Date of Patent: November 1, 2011Assignee: Lockheed Martin CorporationInventors: Antonio Paulic, Lance Hamilton Benedict
