However, the Navy and Marine Corps especially could be faced with a worthy opponent in a come-as-you-are fight, without the vast support resources that have come to be expected and demanded since the Persian Gulf and Kosovo engagements. For this reason, the committee believes that the ONR ASWT program must continue to maintain detailed awareness of the technical developments of other countries and must ensure that U.S.

Conclusions The committee' s conclusions for the air superiority mission area of ONR' s ASWT program are the following: · Improvements continue to be needed in missile kinematics, enhanced seeker performance, increased off-bore-sight capability, and enhanced warhead lethality. · F.ffort.~ .~ho,~lr1 ha.

In the area of precision strike, ONR's ASWT program is focused on the following themes: · Responsive and accurate fire control, Precision target handoff, and Weapon sensor performance. When fixed targets are attacked, the guidance of existing weapons is generally dependent on a guidance system that uses an inertial measurement unit (IMU)

A coherent program component that addresses the critical problem areas that need attention in both precision strike and naval fire support does not exist within ONR. The ONR effort in precision strike consists of several program components with specific performance goals, base lined relative to 1995 weapon capabilities and time phased for completion by 2005, 2010, and 2015.

efforts to join with, or serve as surrogates for, acquisition, demonstration, and validation, which have been largely eliminated by acquisition reform. Comments on Program Components Because of the diversity and extent of the program components in the precision strike area, the committee believes that it is appropriate to comment on each of the individual major efforts being pursued in this mission area.

This apparently overarching program component includes the four tasks discussed immediately below. Precision Standoff Weapon Control The presentation on precision standoff weapon control made reference to the automatic generation of templates that would simplify the reporting over a weapon data link of data related to objects detected in the field of view of a weapon's sensor.

Weapon Sensor Performance The objective of the weapon sensor performance program component is to maintain a 3-meter circular error probable (CEP) in the presence of adverse weather, clutter, and GPS jamming.

Conclusions The committee's conclusions for the precision strike mission area of the ONR ASWT program are the following: · To meet top-level requirements (performance goals) , an effort is needed to define future strike weapons systems concepts.

. NAVAL FIRE SUPPORT Overview Both the naval fire support and the precision strike mission areas face a common set of problems related to the targeting of fixed, relocatable, moving, and ephemeral targets; automatic target recognition: response time for delivery of weapons on target: warhead lethality: weapon range: and weapon , ~ ~ ~ ~ ~ ~ ~ 1 ~ ~ 1 · ~ ~ ~ ~ , r ~ r.

The naval fire support mission area needs more emphasis on missile solutions. The naval fire support mission area is also deficient in providing program components that address moving targets.

Recommendations Naval Fire Support. Rebalance the program components by increasing efforts on technology for surface-launched missiles for fire support at ranges beyond those expected for ERGMs.

Program components have been structured to reflect these conditions based on input from a 1998 workshop that included resource sponsors and program executive offices (PEOs) .3 The outcome of the workshop was that future technology efforts should focus about 50 percent on near-term technologies that can be used by engineering and manufacturing development programs and 50 percent on long-term S&T initiatives that can be applied to future naval requirements.

It also involves a special projectile shape, which may be costly. ONR has done an excellent job of restructuring its ship-based defense program components using the input from Navy resource sponsors and PEOs referred to above.

The unsteady aerodynamics program components grew out of a practical problem that arose during F-18EIF flight testing. When the F-18EIF is flying at a certain lift coefficient, whether in a turn or in level flight, one wing or the other tends to drop in an unpredictable, capricious fashion.5 If the underlying phenomenon is truly aperiodic, the Navier-Stokes code mav require a large number of repeat · .

Reduce the number of intelligent air vehicles and UCAV projects, and then redirect 6.1 and 6.2 program components toward closer coupling to other important needs of ONR's ASWT program. Surviving 6.1 candidate program components also should be scrutinized carefully for scientific merit.
