NIFC-CA is an extremely signifcant current example of cross-domain fires, as it involves the use of an air-asset, martime surface vessel and, quite possibly, land-targets as well. 

The Navy previously talked about developing longer-range precision rounds to fire from the 5-inch guns on surface ships, further enhancing its ability to destroy enemy targets on land; one such possibility under consideration is a maritime variant of the GPS-guided 155m round known as Excalibur, however in recent days the Navy has not specified which, if any, precision round the service may be considering for deck-mounted guns. 

While seemingly geared at the vast geographical expanse and land-sea island terrain of the Pacific, “cross-domain” fires are also of great relevance in other strategically vital areas such as the Middle East, Eastern Europe and Africa, Smith said.

The Pentagon plans to increasingly conduct wargames emphasizing "cross-domain" fires against high-end adversaries.
