In 1989 the Advanced Concepts group at LTV studied adding additional stores capacity to the S-3B Viking.
Five new stores loads were studied including: Four AGM-88 HARM Missiles, Four AGM-84 Harpoon missiles,
Two AGM-136 Tacit Rainbow missiles, and Two AIM-9 Sidewinder Missiles.

A number of different combinations of these missiles were envisioned. The major limitation was the 2,500lb limit
to the wing pylon on the aircraft. An additional concern was the asymmetric effects caused when only one of the
two weapons on the pylon was deployed.

Here are a few drawings of the reviewed twin weapon adapters and the possible Sidewinder installation.

Also AIBF,ultra-STOL concept,fitted with four engines;

To assess the AIBF ultra-STOL performance  potential,the experimental data
developed by the NASA/USAF/Lockheed large-scale tests for the AIBF concept
were used for analyzing the deck performance of a typical sea-based aircraft
configuration.Figure 10 depicts this conceptual AIBF ultra-STOL configuration
which had an aspect-ratio  7.73 wing of 68-ft span and a wing area of
598 sq.ft.The power plants were four TF34-GE-2 turbofans. It was assumed
that the TF34/AIBF installation was similar to the AIBF  application scheme
shown in Figure 1b and that the flap setting for both takeoff and landing
configurations was 30 degrees.
