The "adaptive" characteristic apparently refers to the idea that the explosive yield can be controlled to suit target type and engagement scenario. Work on achieving directional control of warhead effects based on information received from fuzing sensors was not mentioned, so is assumed to be taking place in other parts of the ONR program.

The work is well coupled with the national effort in energetic material the National Energetic Material Program and the Joint DOD/DOE Office of Munitions memorandum of understanding. 1As presented to the committee, this D&I thrust encapsulates Code 351's weapons-related efforts in the Missile Defense Future Naval Capability (MD FNC)

However in urban warfare and in the neutralization of tunnels, caves, and buried enclosed structures, the long-duration pressure and thermal pulse can significantly enhance target defeat. Thermobaric explosives work is aimed at eventual Navy participation in an advanced concept technology demonstration (ACTD)

Work in penetrationsurvivable explosives aims to develop explosives that perform well in adverse thermal and shock environments so they can be used as payloads in hypersonic weapons against deeply buried targets. Early successful experiments were conducted using a very insensitive DOE explosive based on triaminotrinitrobenzene to demonstrate this capability.

Congressional add-on funds are also being used for lethality testing and mission analysis and for lethality tests against specific materials, such as ceramic radomes at the White Sands Missile Range (WSMR) HEL test facility.

Recommendations For reasons of propagation, 1 micron has been selected as the preferred laser operating wavelength. However, the presence of such an HEL in the fleet at sea and in littoral environments presents a danger to the eye that would require compensating changes in Navy operating procedures.

The 155-mm gun with a scaled-up version of ERGM proposes to extend the range to 100 nmi, thereby encompassing a higher percentage of the target set. The generic problems facing the use of guns in the mission of fire support are the following: · Targeting of fixed, relocatable, and moving targets, · Target recognition, · Total response time for delivery of weapons to the target, · Warhead lethality, · Weapon range, · Weapon guidance, and · Rate of fire.

From page 28... ...
ONR programs in this area have provided useful analysis tools for aerodynamic predictions of range for various low-drag shapes and for warhead lethality predictions. Recommendations The committee endorses the work being performed or already completed in the projectile area.

From page 29... ...
The longer range fire missions are probably better handled by solid-rocket-propelled ballistic missiles. The attendant barrel erosion problems lead to the need for barrel liners, and high setback acceleration requirements and the logistic issues associated with a gun round that is large (and requires a double tamp loading)

From page 30... ...
The committee notes, for example, that the holy grail of automatic target recognition under harsh, deceptive, and dynamic environments remains as far in the future as ever under the current Code 351 program. Even if these cutting-edge technologies are being addressed elsewhere, their omission from the Code 351 agenda slows the pace with which they could be introduced to related FNC processes.

Precise Tactical Targeting Findings The goal of this subtask is to develop a systematic approach for using a standoff platform to provide affordable, near-real-time target information for GPS-guided weapons, with initial operational capability of 10-m accuracy in 2007 and demonstration of 1-m accuracy in 2010. The approach uses distant GPS control station data for improved platform location accuracy, low-cost inertial measurement of

. However some aspects of propulsion and aeromechanics also appeared in several other briefings, including those on adaptive ordnance, mission response ordnance, precision strike navigator, high-speed antiradiation demonstration, and gun barrel erosion (and fatigue)
|
From page 33... ...
The goals include a significant increase in rocket propulsion capability by 2010 by increasing weapon kinematics, decreasing weapon size, and decreasing the number of weapon systems. The roadmap includes an air-launch demonstration, an advanced air-to-air rocket technology demonstration, a surface launch propulsion demonstration, and a gun-launched rocket demonstration.

From page 34... ...
Fortunately, and very recently, one might even say "magically," a technology has been developed that eliminates erosion and ensures structural integrity the integrated omnivector cone (INOVEC) phase II demonstrator.
