Normal sudoku rules apply. (place a digit in each cell such that every column, row, and marked 3x3 box contain each digit exactly once)

All battleships must be placed in the sudoku grid exactly once such that no battleships touch orthogonally or diagonally, and any digits given on your battleship display match that cell in the sudoku grid. Unlike standard battleship, you may not rotate your pieces.

Cage clues are the *sum* of all battleship cells along the given row, column, or diagonal. Clues with multiple arrows sum separately for each arrow.

Circle clues are the *number* of battleship cells in the given column or diagonal. Circle clues in the sudoku grid correspond to the digit in their cell. These clues are not battleship cells, and start from the arrow.

I made this for Zetamath's Coloring Challenge! I haven't seen battleship sudoku combined with little-killer-esque clues before so I'm excited to see how this is received! Thank you DarthParadox, Nebula, and mathpesto for testing :)
