The Carrier-Surface Combatant Relationship
Yesterday I talked a bit about large-deck carriers' traditional doctrinal roles in helping obtain localized, temporary sea control for naval battleforces. In particular, I noted how the air wing historically served as the outer screen in a battleforce's layered defenses. The battleforce ordnance inventory management challenge represents a major reason why this is so.
Battleforces need to be able to hold their own against fierce opposition while operating within a combat theater, even if those operations are designed to last only a few days at most. They may need to fight their way into the most hotly-contested areas during a major war, and it is quite likely they will need to fight their way back out. Shipboard offensive and defensive missile expenditures during combat operations consequently may be considerable. While it is critically important that the U.S. Navy soon develop means for replenishing shipboard vertical launchers underway, it nevertheless seems highly unlikely that the reloading process (or the associated logistical support ships) would be risked in ‘frontline’ areas where the threat of minimal-warning attack by the adversary was high.[i] In contrast, large-deck carrier ordnance magazines are sized to permit continuous, agile ‘reloading’ of a battleforce’s outer screening layers throughout multi-day combat operations. As in the past, doctrine and tactics can define the battleforce’s division of sea control labor between the air wing and surface combatants such that the latter’s missile expenditures are economized as possible to sustain battleforce operations for several days under heavy opposition.

For illustrative
purposes, let’s say the main contested zone at the beginning of a maritime
conflict between the U.S. and another great power stretched out as far as 1500nm
from the latter’s coast.[ii]
At or beyond this zone’s periphery, U.S. battleforce operations would focus on defending
the maritime lines of communication to theater allies’ rear-area bases and
commercial hubs. Within the zone’s outer or middle sections, battleforce tasks might include
raids designed to seduce and attrite enemy maritime forces, disrupt enemy operations,
or serve as feints supporting friendly operations elsewhere. Contested zone
operations might not only be conducted as sea control-enabling precursors for subsequent
power projection operations, but also might be used to maintain or reestablish lines
of communication to isolated frontline forces and territories resisting the
enemy’s offensive. They might even be used to temporarily dispute or deny the
enemy’s sea control in select frontline areas; for example, to situationally
support friendly submarine operations by harrassing or suppressing enemy
Anti-Submarine Warfare forces. Destroying enemy maritime forces at their bases
is certainly preferable in theory, but if this is not possible for military or
political reasons, the use of brief operations that strive to selectively draw
them into battle at sea under conditions favoring friendly forces is next best.
Major war operations would
be shaped by how the relative threat within the operational area, the number of
high campaign-value
forces available in the theater, and the campaign objectives driving any given
operation meshed with the theater commander’s risk tolerances. Under many
scenarios, the necessary size of a sea control ‘moving bubble’ and the amount
of friendly firepower that must be massed within it may require dispersed yet
mutually-supporting multi-carrier task forces as was envisioned in Cold War
operational concepts.[iii] In
tactical situations where the risks posed to carriers are judged by the theater
commander to be excessive, it is conceivable that multi-mission Surface Action
Groups (SAG) detached from or independent of carrier groups might be sent
forward as raiders with sea control/denial or power projection tasks. Should
this occur, carrier-based fighters—supported by battleforce-organic Airborne
Early Warning (AEW) and aerial refueling assets, with augmentation by
land-based AEW and tanker aircraft as possible—might screen SAGs throughout
their contested zone missions. Carrier-based fighters might likewise be sortied
forward if a SAG makes heavy contact with adversary forces, or be used to cover
an ordnance-depleted SAG’s retirement from the contested zone. The same would
be true for providing similar support to maritime forces operating at the
‘frontline’ at the beginning of a war.[iv] Fighters
based on land within the contested zone could also render this support, but
because their doing so would be predicated on their basing’s survivability and
logistical lines of communications’ defensibility, carrier-based fighter
support remains a necessary hedge within operational plans.
The key takeaway from
this discussion should be that U.S. battleforce operations should not be
conceived as singular ‘charges of the light brigade’ deep within the contested
zone at the beginning of a war followed
by the establishment of long-duration ‘frontline sanctuaries’ for carrier
operations. Rather, they should be conceived as sequential (or if multiple task
forces are involved, perhaps parallel) hit-and-run operations that gradually
degrade an adversary’s ability to fight effectively in the contested zone’s
outer sections, which in turn creates the conditions that allow the process to
be repeated for the zone’s middle sections.
