The trip by Army General Michael "Erik" Kurilla, head of U.S. Central Command, is the latest by a senior U.S. official to Israel ahead of an expected ground assault by Israel's military in Gaza.
The Pentagon is also rushing weaponry, including air defenses and munitions, to Israel.
"I'm here to ensure Israel has what it needs to defend itself, particularly focused on avoiding other parties expanding the conflict," Kurilla told Reuters, which is traveling with him, in brief remarks before landing.
A U.S. official told Reuters Kurilla was scheduled to hold high-level meetings with Israel's military leadership, ensuring a clear understanding of the close U.S. ally's defense requirements.
Clashes this last week have been the deadliest in the Lebanon border area since a 2006 war between Israel and Hezbollah.
