Wachtell Lipton Rosen & Katz, Skadden Arps Slate Meagher & Flom and Cleary Gottlieb Steen & Hamilton have secured roles on the $30bn (£23.21bn) acquisition of Rockwell Collins by United Technologies.

Wachtell and Cleary are acting for US jet engine-maker United Technologies. Cleary's Brussels based team is being led by competition partner Christopher Cook.

Skadden is advising Rockwell Collins, which produces electronics for aircraft including the F-35 fighter jet (pictured).

The Skadden team is being led by Chicago M&A partners Charles Mulaney and Richard Witzel. Other partners involved include New York competition partner Clifford Aronson and Brussels competition partner Frederic Depoortere.

The transaction is set to close by the third quarter of 2018, subject to approval by Rockwell Collins' shareholders and the required regulatory approvals.

Under the deal, the companies' aerospace systems businesses will be combined to create a new business unit called Collins Aerospace Systems.

Both Wachtell and Skadden have secured advisory roles on some of the largest M&A deals this year. Wachtell was instructed by Whole Foods in June, when Amazon agreed to acquire it for $13.7bn (£10.7bn). Amazon turned to Sullivan & Cromwell on the deal.

Meanwhile, Skadden was called up by Vantiv in August for its £9.3bn merger with UK payment processor Worldpay. Worldpay is being advised by Allen & Overy (A&O).
